NBC Sports Boston's coverage of Celtics-76ers starts at 6:30pm Wednesday with Celtics Pregame Live, and then Mike & Scal have the call of the game at 7:30pm.

Kemba Walker hasn't been Jaylen Brown's teammate for very long; the two players haven't even played a regular-season game together yet.

But after getting an up-close look at Brown during FIBA World Cup play, training camp, and the preseason, Walker likes what he sees from Brown, who inked a four-year contract extension worth up to $115 million on Monday afternoon.

The deal comes just three and a half months after Walker signed a $141 million contract with Boston — and to Walker, this latest deal reaffirms the franchise's commitment to winning.

“I know what these guys are all about, man, and this organization, they want to win,” Walker told Jared Weiss of The Athletic Monday afternoon. “You have to invest in the players, and Jaylen, he deserves it. I’m super, super happy for him.”

Had Brown not signed on the dotted line Monday, he would've been a restricted free agent next summer. But now he can play out the season with job security instead of potentially getting distracted by questions about playing for a new contract.

“I’m not saying Jaylen would do it, but it can be hard for a guy to be playing for a contract just for one year,” said Walker, who marveled at Brown's intelligence on the court. “He could’ve not took it and played the year out to showcase himself to other teams or even the Celtics again. Now it’s just less pressure. Now he really can just play basketball, work on his game and just continue to get better without worrying about his contract situation. I think it’s a huge burden off his back.”


It sure looked like there was a burden off both Brown and Danny Ainge's backs when the pen was put to paper Monday. Brown posted a picture of the big moment on the Instagram page for 7uice, his official brand. 

Brown's big week continues Wednesday when the Celtics open the season against the 76ers — and then on Thursday, when he celebrates his 23rd birthday.
