The Dallas Mavericks sent shockwaves around the NBA by trading for Rajon Rondo. The Mavs acquired the All-Star point guard by giving up role players Brandan Wright, Jae Crowder, Jameer Nelson and draft picks to the Boston Celtics. The Celtics will reportedly receive a first-round pick in the 2015 draft and a second-rounder in 2016.

Rondo joins a Mavs squad that features future Hall-of-Famer Dirk Nowitzki, Monta Ellis, Tyson Chandler and Chandler Parsons. The new Dallas starting five easily becomes one of the most potent in the Association, and it gives Dallas coach Rick Carlisle another chess piece to work with.

Rondo could fill the Jason Kidd role that worked perfectly in 2011 when Dallas won the NBA title. Rondo does need to score to be effective. He’s a walking triple-double — just like Kidd — on offense and on defense he provides the Mavs a terrific on-the-ball defender who can stick guys like Tony Parker, Russell Westbrook, Stephen Curry and Chris Paul.

Carlisle should send his former Boston buddy Danny Ainge a Christmas card because the Celtics president of basketball operations just gift-wrapped him a wonderful holiday present. With Rondo, the Mavericks went from a very good team into one of the elite squads in the Western Conference.

“[This trade] puts [Dallas] in a position to win a championship,” ESPN analyst and former NBA player Jalen Rose said on The Grantland Basketball Hour. “They are going to be a terrific team in Dallas. [Rondo] is going to balance the floor. This guy is a floor general. He makes players around him better.”

The Mavericks are now loaded in the backcourt. Rondo and Ellis are the clear-cut starters; J.J. Barea will likely back him up at the point and Devin Harris can play either guard position. Raymond Felton is still on the roster, so Carlisle will have to make a decision who to sit because you can’t rotate five guards. It’s a nice problem to have.

If there’s a negative side to the deal it’s the Mavericks’ weakened frontcourt. Wright was a solid backup center who kept Tyson Chandler from having to play a ton of minutes. Now, Tyson will have to extend himself a bit more.

The trade ends Rondo’s nine years with the Celtics, a stretch that includes an NBA championship in 2008 and a trip to The Finals in 2010. Rondo carved out his niche in Celtic lore with some memorable playoff moments. None better than when he dislocated his left elbow in Game 3 of the playoff series against the Miami Heat in 2011. Rondo courageously returned to the game, arm dangling, and led the Celtics to an emotional win at the TD Garden.

But when the Celtics started peeling off their championship squad, Rondo — who is coming off ACL surgery last season — didn’t fit into the rebuilding process. The Celtics are clearly looking into the future, and Rondo was in the way of that plan. They drafted point guard Marcus Smart in 2014, which led many to believe was the beginning of the end of the Rondo era in Boston.

Rondo’s statistics declined in some key areas this season. His free throwing shooting percentage is a career-low .333 and his scoring average dipped to 8.3 points per game, his lowest since his rookie season of 2006-07, when he averaged 6.4.

“We all know what he does really well,’’ Celtics coach Brad Stevens told The Boston Globe. “There’s very few people in the game that can do some of the things he can do and you can probably extend that — the way he passes the ball and the way he gets other people the ball — you can extend that to the history of the game. He’s really done a lot of good things.”

Through 22 games this season, Rondo is leading the league in assists (10.8). He also is averaging a career-high 7.5 rebounds. He has also put up three triple-doubles. He has averaged 11 assists per game in four out of the last five seasons. He’s only 28 years old, so he is still in the prime of his basketball career.

“The last two years he was playing like a guy who didn’t want to get hurt,” said Grantland editor Bill Simmons, a longtime Celtics fan. “He’s gonna go to Dallas and he’s gonna be awesome. He always rose to the occasion. Now that he’s on this [Dallas] team, that’s perfect for him.”

With 28 seconds left in Game 7 of the Eastern Conference finals, the Miami Heat had a double-digit lead and the Boston Celtics were running on fumes. Celtics coach Doc Rivers knew it was time to wave the white flag and pull his starters off the court.

‘We had nothing left,” Rivers said. ”That’s how it felt, as a coach . . . But overall, I don’t know if I’ve ever had a group like this.”

There was a lot of emotion on the Celtics’ sideline as Kevin Garnett, Paul Pierce, Ray Allen, and Rajon Rondo headed for the bench. Garnett and Rivers shared a poignant moment as the two men hugged it out while time ticked away on what could be the final time Boston’s Big Three — plus Rondo — will ever wear Celtic green.

In the five-year era of the “Big Four” — or the Fantastic Four, whichever you prefer — the Celtics posted a 69% winning percentage during the regular season, won five Atlantic Division titles, made three trips to the Eastern Conference finals, reached the the NBA Finals twice, and raised one championship banner.

That one NBA title will be the signature moment for the Fantastic Four, but the group also left a lot of titles on the table because of injuries, trades, and one freak elbow injury to Rondo in the 2011 playoffs.

“I wish we had a healthy run. This team won a title, got to another one lost in Game 7 [against the Lakers in 2010] where they had a shot to win. Got to the Eastern Conference final one game away on the road banged up,” Rivers said. “Because of really Kevin’s injury I don’t know if we could have gotten any more out of the group. I would have loved to have seen this team in this whole stretch where Kevin was injury free.”

The injury Rivers was referring to was the knee injury Garnett sustained during the 2008-09 season, which knocked him out of the playoffs and it took KG a full season to completely recover from it.

It is not a certainty that general manager Danny Ainge will break up Boston’s Fantastic Four but, because of age and expiring contracts, it will be very difficult to keep the nucleus of the Celtics with Garnett and Allen becoming unrestricted free agents this summer.

The group knew all season long, especially during the playoffs, Who knows what next season could bring.

Boston battled injuries all season, all the way to the end. Allen said he’ll need surgery soon to repair bone chips in his right ankle. Pierce has been playing through a sprained knee ligament.

It all hurt. Nothing hurt more than the final buzzer Saturday night.

”It’s probably the worst feeling that we feel, in our lives, in our careers,” Allen said. ”There’s nothing you can do about it. There’s one team that wins that last game. We want to be that team every year. We’ve been through a lot. We’ve won a lot of games. At the end of every season, it always feels like it’s it.

”This one hit me hard,” Allen continued. ”We wanted it so bad.”

Allen fought through a painful ankle injury for much of the playoffs while Pierce played through a banged up knee. Garnett, 36, had a resurgence in the playoffs and looks like he’s got a couple of good years left. Rondo and Pierce remain under contract so they’ll be back. There is a strong possibly that Garnett will return to Boston, but Allen seems to be headed into free agency.

The loss of Allen won’t hurt as much because the Celtics have Avery Bradley and Mikael Pietrus to plug in his spot. Losing Garnett, however, would be devastating.

“Well, [Kevin’s] been everything for my career,” Pierce told ESPN Boston. “Just his locker room presence, his desire, his determination, his leadership. I’ve said it before, when Kevin first got here, he really changed the culture of everything we did around here — from the practice habits to on the court, just the discipline. He made everybody accountable, from the ball boys to the chefs to the guy who flew the plane. Everybody was accountable.”

Pierce continued: “It was tremendous to just have him around. The culture he brought — it would be great for me to end my career with Kevin. I have a couple years left, and who knows what his future’s going to bring. Hopefully management can do something to bring him back, maybe add some pieces to this team, that we need, to get over the top. If not, it’s been a tremendous run.”

The two biggest losers, without a doubt, during NBA “Tradefest” were the New York Knicks and the Boston Celtics.

The Knicks got their man in Carmelo Anthony, but they practically gutted their team to get him. On the outside, the deal was a no-brainer and seemingly well worth a three-month headache. Melo is the most celebrated NBA superstar the Knicks have had since Patrick Ewing. Sorry, Amare. You are Robin to Carmelo’s Batman.

However, on the inside, the Knicks could have signed Anthony during the summer and kept all their pieces together. Anthony never intended to sign Denver’s offer sheet from the get-go. It was all posturing on his end, and to the Nuggets’ credit they never budged. It was a game of “who blinks first” and fortunately for Denver Knicks CEO James Dolan couldn’t stay patient and went all in too soon. He sent three quality players – Danilo Gallinari, Raymond Felton and Wilson Chandler – to Denver, making the Knicks’ roster extremely thin.

The move falls totally on Dolan’s lap (with Isiah Thomas in his left ear) because if it were up to GM Donnie Walsh, the Knicks probably would have folded their cards last week and simply waited for Melo to walk through the front door of Madison Square Garden sometime in July with pen in hand itching to sign a contract with the team he so dearly wanted to play for. That would have given the Knicks are very potent lineup of Amare Stoudemire, Gallinari, Chandler, Felton and Anthony.

Dolan better hope Chris Paul lands in New York in 2012.

The other team that took a hit at the trade deadline was Boston. GM Danny Ainge may have caused a minor earthquake in Massachusetts by sending two very popular players in starting center Kendrick Perkins and backup point guard Nate Robinson to Oklahoma City in exchange for forward Jeff Green and center Nenad Krstic.

After losing in Denver on Thursday, just hours after the deal was done, an emotional Kevin Garnett – without question the heart and soul of the Celtics – had a difficult time coping with the loss of his teammates, telling reporters that it was an extremely “tough day” and he feels like he just “lost a family member.”

Perkins was not only the anchor of the Celtics interior defense but he was also a huge part of a Boston starting five, along with KG, Paul Pierce, Ray Allen and Rajon Rondo, that has never lost a playoff series when they are all healthy. That record will remain intact because Big Perk will no longer man the middle for Gang Green, grabbing loose balls, setting picks, battling Dwight Howard and Pau Gasol in the paint, intimidating refs and protecting the basket. All the intangibles that Perkins brings to the court will be missed.

Ainge was the toast of Beantown in 2007 when he acquired KG and Ray Allen and surrounded head coach Doc Rivers with a very capable roster. With this recent transaction, Ainge’s standing in the Celtics community is on thin ice. If the Celtics falter in the playoffs, Ainge could be roasted in Beantown.
