Kemba Walker's infectious positivity and great interpersonal skills are already the talk of the town in the Boston Celtics' locker room.

Former Charlotte Hornets teammate Marvin Williams isn't surprised by the least to see his longtime friend thriving on a new team:

“Not surprised,” said Williams when asked about Boston's hot start, according to ESPN's Tim Bontemps. “Not even a little bit. He fits right in. His personality is so infectious, man. He's somebody that you want to be around. He's somebody that you always want to go play with.”

This isn't an act for Walker, but rather his contagious personality flourishing in a bigger market and on a large stage. He's just a happy guy:

“I'm really just being myself,” said Walker. “I'm really just genuinely happy for guys and my teammates. I love when guys have success. I've had a lot of success in my career, and I want guys to have great success.”

This wasn't any more evident than the Celtics' recent overtime loss to the Los Angeles Clippers, in which Walker was more than happy to see Celtics teammate Jayson Tatum take the last shot to send the game to overtime, one which the Celtics ultimately lost in the extra period. Walker couldn't ask for any more from Tatum:

“Jayson had that opportunity to get that last shot, and he made it,” Walker said. “What more can I want? He won, he made a last-second shot, it was an amazing game, and I'm just happy. I'm just happy for my teammate.”

Dialing back a season ago, Kyrie Irving was fuming when Tatum had taken the decisive shot in a loss to the Orlando Magic, but Walker has a different outlook:

“For me, it's just the nature of this sport, like a team sport,” said Walker. “You don't want nobody to be unhappy. You want everybody to play with joy, play with freedom and have fun.”

Walker was this great teammate all along on the Hornets, but without the personnel to clearly reflect it. Now that he has it, the infectious joy of playing team ball has resulted in a 12-4 record and great ambitions for the rest of the 2019-20 season.
