The Boston Celtics had the Miami Heat on the ropes last postseason when they nearly pulled off the upset. The Celtics held a 3-2 series edge, but lost the final two games and the Heat advanced to the NBA Finals.

The loss to Miami forced Boston to make some changes in the offseason, cutting ties with Ray Allen and upgrading the bench. On Wednesday, the Celtics reportedly signed guard Leandro Barbosa to a one-year contract worth the veteran’s minimum salary.

Barbosa has played for three teams in his career, most recently with the Indiana Pacers. He is still just 29 years old and can be a fine addition to the Boston bench. He has averaged 12.5 points per game, and played in 588 games during his nine-year NBA career.

Boston seems to have cornered the market on combo guards — they also added Jason Terry, one of the best sixth men in the league. The Celtics also have Avery Bradley, who will start the season rehabbing from surgery on both shoulders. They also brought in veteran shooting guard Courtney Lee.

To be honest, signing him surprised me a little bit. They have Rajon Rondo, a top-five point guard, and once Bradley heals they will have five guards deserving playing time. I guess they feel like having too many is better than too few. Barbosa gives the Celtics a guard who, even though undersized at 6 feet 3, is capable of playing both backcourt positions. He has made his reputation as a penetrating guard who likes to take it to the rim and score in the paint. Think of a poor man’s (or a homeless man’s) Allen Iverson.

Adding Barbosa doesn’t make them the favorites in the Eastern Conference, but it definitely gives them a lot of depth and helps increase their chances of being able to possibly beat the Heat in what should be a great rivalry.

All-Star center Dwight Howard is on his way to Hollywood to join forces with Kobe Bryant, Pau Gasol and Steve Nash. (ASSOCIATED PRESS)

Deron Williams returned to the Nets, Steve Nash and Dwight Howard are headed to Hollywood, and Jason Terry is moving from Dallas to Boston. The 2012 NBA offseason had plenty of franchise-altering moves — most of which benefited the major markets. So much for competitive balance. Some teams did better than others (ahem! Lakers), while most stayed above the fray and maintained status quo. OneManFastBreak.net highlights the winners and losers:

LOS ANGELES LAKERS

Mitch Kupchak locked up executive of the year with his two monumental moves this summer. He pried Nash from the Phoenix Suns (a division rival) to give Kobe Bryant the best point guard he’s ever had. Then, he shocked the basketball world by acquiring the best center in the world without giving up all-star Pau Gasol. With Nash, Kobe, Ron Artest, Gasol, and Howard, the Lakers have easily the best starting five in the NBA and arguably the greatest starting five in basketball history. The Lakers’ Fab Five are armed with two league MVPs, two defensive players of the year, and the most skilled big man in the game. Even at age 38, Nash is still a terrific playmaker and he’ll make sure Gasol and Howard will get their touches on the offensive end. The Lakers were eliminated in the second round of the playoffs mainly because their offense faltered and did not execute. Nash will step into the role of offensive coordinator and he’ll instantly make the Lakers a lethal offensive team. Howard adds to the Lakers’ great history of dominant centers, joining Mikan, Wilt, Kareem, and Shaq.

BOSTON CELTICS

Boston reached the Eastern Conference finals in 2012 despite a gimpy Paul Pierce and a hobbling Ray Allen. Priority No. 1 in the offseason was to bring back Kevin Garnett. The Big Ticket re-signed with the Celtics, assuring he’ll retire a Celtic, and then general manager Danny Ainge added more firepower on offense by signing shooting guard Jason Terry, a member of the Mavericks’ 2011 championship squad. Terry addresses a major issue for Boston: scoring. He’ll help the Celtics avoid long scoring droughts with his ability to create his own shot and not have to depend on point guard Rajon Rondo to feed him the ball off screens. Terry can also serve as a backup point guard, giving head coach Doc Rivers more flexibility on offense.

BROOKLYN NETS

Deron Williams was arguably the biggest catch of the summer, and he was the first to decide where he wanted to play. Williams re-signing with the Nets gives the Brooklyn franchise a centerpiece and a name on the billboard of the team’s brand new arena. But Williams won’t be alone on that billboard. All-Star guard Joe Johnson was acquired from Atlanta, giving the Nets a studly backcourt combo and plenty of firepower. The team also re-signed power forward Kris Humphries to bolster its frontline. Now, if the Mikhail Prokorov can convince Dwight Howard to join the Brooklyn party then the Nets will be the biggest winner of the summer.

HOUSTON ROCKETS

Daryl Morey caught a lot of flak for letting Goran Dragic, Kyle Lowry, and Luis Scola leave town without compensation and then signed Jeremy Lin to a $25-million contract. On the outside, it looks like the Rockets are throwing in the towel. But if you look closely, Morey is fielding a team that is cap-friendly. Lin is going to be The Man in Houston, picking up the Asian fan votes vacated by Yao Ming. Lin should fit in nicely in Kevin McHale’s free-flowing, pick-and-roll heavy offense, and that’s likely the biggest reason why he chose Houston over New York (oh, the $14.8 million on the third year of the deal ain’t bad either).

The Rockets are cleaning house for the right reasons. First-round draft picks Jeremy Lamb and Terrence Jones are very good young players, and they should figure into McHale’s rotation from the start. The Rockets’ offseason is a perfect case of addition by subtraction.

PHILADELPHIA 76ERS

Ever since Allen Iverson left town, Philly fans have been craving for star. Enter Andrew Bynum. Bynum gives the Sixers their first significant low-post threat since Moses Malone and he immediately turns the Sixers into one of the top teams in the Eastern Conference. He’s arguably the second-best center in the NBA and, at 24, his ceiling is so high he has only begun to scratch the surface of the roof. Bynum, who won two championships with the Lakers, will be The Man in Philadelphia and his big body (7 feet, 290 pounds) in the paint will alter the way the Sixers play on both ends. Joining Bynum in Philly are free agents Jason Richardson, Nick Young, and Dorell Wright.

DALLAS MAVERICKS

When Deron Williams announced his decision to stay with the Nets instead of joining the Mavericks, Frank Isola of the New York Daily News tweeted this gem: “Russian 1, Cuban 0.” That, of course, is in reference to the Nets owner, Russian billionaire Mikhail Prokhorov, getting over Mavs owner Mark Cuban, who was hoping to lure Williams to play in his home state of Texas. The Williams decision had a domino effect in the Mavs’ plan. Dallas’ all-out-effort to land Williams made Kidd a little leftout. Nobody likes to be second choice, so Kidd chose his own path by signing with the Knicks. But Kidd wasn’t the only Mavs guard to defect. Longtime Maverick Jason Terry, a member of the team’s 2011 championship team along with Kidd, is taking his talents to Beantown and join the Celtics. So, if you’re still keeping score, it’s now Free Agency 3, Cuban 0.

CHICAGO BULLS

The only good news this summer for Chicago are the improving health of Derrick Rose coming off knee surgery and the return of Kirk Hinrich, a big piece of the Bulls’ resurgence in 2008. But take away the Hinrich signing and the Bulls have had a nightmarish offseason. Kyle Korver, Ronnie Brewer, John Lucas, C.J. Watson, and Omer Asik are all gone. All five were important cogs off the Bulls bench. Korver was arguably the Bulls’ best player in the fourth quarter, while Brewer and Asik are very good defenders. Lucas and Watson are not all-star players, but they both did an admirable job in Rose’s absence. Continuity is a big part of a championship team, and the Bulls are basically starting over with an entirely new bench unit (Marco Belinelli, Vladimir Radmanovic, and rookie point guard Marquis Teague) for the 2012-13 season. Belinelli is nowhere near the shooting Korver is, and Radmanovic is not someone you want guarding LeBron James — or any small forward for that matter — in the fourth quarter.

NEW YORK KNICKS

Phil Jackson calls the New York Knicks a “clumsy” team, and the Knicks tripped over themselves this offseason by not getting Nash. Then the Knicks made a bold move by signing veteran point guard Jason Kidd. The former Mavericks playmaker could turn out to be a better option because Kidd won’t mind running Mike Woodson’s isolation offense. Then the Knicks signed Raymond Felton, which was a little bit of a head-scratcher considering Felton was grossly out of shape last season and now he’s being rewarded for his unprofessionalism. The Felton signing basically forced fan favorite Jeremy Lin out of the rotation, and now New York enters the season the same way they left it — too many players playing the same positions. Lin was a cash cow for the MSG network and time will tell if Lin fans will keep following the Knicks.

ORLANDO MAGIC

In his letter to Magic season ticket holders, CEO Alex Martins wrote: “We look forward to this next chapter of Magic basketball and remain committed to our mission: To be world champions on and off the court, delivering legendary moments every step of the way.” Hmm. In order to win a championship, you must first qualify for the playoffs and, without Howard, Orlando will be far from being a playoff contender for the next few years. Martins and general manager Rob Hennigan were put in a tough spot. Howard made it clear that he wanted out of Orlando, but Martins and Hennigan failed to get the right deal. Sure they got some draft picks, but those won’t matter unless they’re lottery picks. It took Orlando nearly a decade to recover from the breakup with Shaquille O’Neal. When Howard came along, he made Orlando love basketball again. After eight years of basketball bliss, L.A. swoops in and breaks Orlando’s heart yet again. It’s like losing another girlfriend to the same guy 16 years later.

Dirk Nowitzki gets a little too excited after an alley-oop dunk by one of his teammates.

It appears that Dirk Nowitzki has not been able to shake off the hangover from the Dallas Mavericks’ 2011 championship party because the way he reacted after an alley-oop dunk by teammate Brandan Wright against the Minnesota Timberwolves on Jan. 25, Dirk sounded like a college student partying at Oktoberfest.

On a night when the Mavericks got their 2011 championship rings, Nowitzki was helping with TV commentary when Jason Terry picked up a loose ball and dished it off to Wright for a spectacular slam. That play not only got Dirk off his seat, but he started screaming “Shut it down! … Let’s go home!” His teammates were probably listening because the Mavericks did shut it down, and the Timberwolves went on to spoil the Dallas party with a 105-90 victory. Watch and listen:

Mavericks guard Jason Terry is ready for takeoff, especially in the fourth quarter. (GETTY IMAGES)

TNT’s Kenny “The Jet” Smith has said on more than one occasion that Jason Terry got his “Jet” nickname not because of his game, but because it stood for his full name: Jason Eugene Terry.

After Terry’s performance in the 2011 NBA Finals, Smith may have to revisit his little jab at the Mavericks guard. And Terry may have picked up a new nickname as well: The Closer.

When Mavericks franchise player Dirk Nowitzki struggled in the early part of Game 6 in Miami, it was Terry who shouldered the load with 19 points in the first half. Once Nowitzki regained his shooting touch, the Mavericks took off and shot their way to a 105-95 victory to claim the Larry O’Brien Trophy.

It was Dallas’ first championship as an NBA franchise, and although Nowitzki was named MVP of The Finals, it was Terry who complemented Dirk and took some pressure off him when it mattered most – the fourth quarter.

“That’s my job. All season long and every since I’ve been a Maverick I’ve been a guy that in the fourth quarter they’ve depended on either make plays or make shots,” Terry said. “I really relish in that role, and regardless of what’s going on for three quarters of the game in the fourth quarter I know I’m depended on to come through.”

Nowitzki was absolutely magnificent down the stretch in each of the games. He scored 62 points in the fourth quarter in the six games, tying the combined total for Dwyane Wade (44) and LeBron James (18). But right behind Wade in fourth-quarter scoring is Terry with 31.

“He was unbelievable,” Nowitzki said of Terry, who finished with a game-high 27 points in the series-clinching Game 6. “He watched me struggle early and he took it upon himself to really attack and look for his shot, and get going early. Oh man, he kept coming all night long and he was phenomenal.”

Nowitzki added, “On one timeout, he kept pushing me and kept telling me, ‘Remember ’06! Let’s not let it happen again.’ ”

In the games the Mavericks lost in the 2011 Finals, Terry was shutout in the fourth and was ineffective. In the games the Mavs won, Terry was a total play-maker and made big-time shots, especially in the pivotal Game 5 in Dallas.

There was a stretch in the final two minutes of the game in which Terry carried the Mavs. When the Mavs went down 100-97, Terry buried a 3-pointer to tie the game at 100. On the next Mavs possession, he found Nowitzki on the baseline for a dunk to give Dallas the lead. Then, with 1:33 remaining, he drove to the basket, blew past LeBron, drew three defenders and kicked the ball out to Jason Kidd for a 3-pointer to build the lead to five. He delivered the dagger shot when he drilled a three from the American Airlines Center logo right in the face of LeBron to give Dallas a 108-101 lead with 33 seconds left in the game.

“During periods where Dirk was out of the game, we were going to him and he was delivering,” Mavericks coach Rick Carlisle said of Terry after Game 5. “It’s the total game that we’ve all been preaching to Jet really since the playoffs began.”

When the season began, Terry inked a tattoo of the Larry O’Brien Trophy on his right bicep. It was bold and very brash move for someone who has only been to the NBA Finals once in his career. When Terry was asked what he would do if the Mavs don’t win the NBA title, he said he’d remove the tattoo. Fortunately for Terry and the Mavs, that won’t be necessary.

Don’t let that 12-game winning streak and the inflated overall record fool you. The 2010-11 Dallas Mavericks are not that much better than the 2002-03 Mavericks, or the 2006-07 Mavericks, or the 2009-10 Mavericks. The coaches and players may have changed, but the same problems persist: a soft interior defense and a predictable offense.

A few nights ago, the Mavericks were rolling and blitzing the league en route to 12 consecutive victories. That winning streak was snapped recently by the Milwaukee Bucks. The Bucks for crying out loud! And, to make matters worse, the Mavericks lost at home, where they should never lose to an average Eastern Conference team, which the Bucks are at this point.

The Mavs have never developed that killer instinct to be considered a legitimate contender for the NBA title. They didn’t have it in 2006 when they blew a 2-0 lead in the NBA Finals to the Miami Heat, and they certainly never had it when they got thrashed by the Golden State Warriors in the first round of the 2007 playoffs.

Killer instinct starts with defense, and as long as Dirk Nowitzki is the face of the franchise, the perception (whether it is reality or not) is that the Mavs will always be a soft team. No matter who the Mavs insert at center to pair with Dirk, their defense remains suspect. The scouting report on Dallas: rough them up and they will collapse like the Metrodome roof.

For all the wonderful things Nowitzki does on offense, he is a liability on defense. He’s your typical European big man (Pau Gasol is the exception) who prefers to shoot fadeaway jumpers. In an ideal situation, Nowitzki would greatly benefit from becoming the No. 2 star – much like Gasol when he left Memphis to join Kobe Bryant’s Lakers. Nowitzki is more Kevin McHale than Larry Bird, which is not a knock on Dirk. He’s a very good player, but he’s not a No. 1 guy.

Acquiring Tyson Chandler during the offseason puts a Band-Aid on Dallas’ soft-as-tissue persona, but Chandler alone can’t cure the team’s deficiencies. Chandler is a tremendous help defender but he’s not a good one-on-one post defender. He gets pushed around at times and picks up too many silly fouls, which reduces his aggressiveness. Brendan Haywood is an upgrade from Erick Dampier, but Haywood is a backup center at best.

Another major problem that could resurface in the playoffs is Dallas’ vanilla offense. I love Jason Kidd as a point guard, but he is a liability on offense. No matter how many threes he makes during the regular season, I would still dare J-Kidd to make jump shots from beyond the 3-point line. That was the game plan the Spurs implemented during last year’s playoffs and it worked to perfection. When you have J-Kidd on the court, basically the Mavs are playing 4-on-5 on offense.

Caron Butler was a nice addition, but he is injury prone. Essentially, he replaced Josh Howard in the lineup so Butler is not a true upgrade. The other major acquisition, Shawn Marion, has seen his better days. The Matrix relied on his athleticism for much of his career, and now that he’s a shell of himself he doesn’t impact the game like he once did.

And what about Jason Terry you say? All you need to know about Jet is when the Mavs are out in front, he’ll light it up. But when the Mavs are behind, he’ll disappear. I’d rather roll the dice with Roddy Beaubois than go all in with Jason Terry.

Right now the Mavericks are rolling, but don’t get your hopes up.
