There were a lot of takeaways from today's media session. There's Paul Pierce's troublesome pinched nerve in his neck:

During a game in Phoenix last week, Pierce had to be removed from the game while battling a stinger early in the second half.

"I probably won't be fully recovered from it until the season is over, if I ever do," said Pierce. "I probably have a little bit of nerve damage in my back, part of my neck. It's something that I've been playing through over the last several months. I'm about as healthy as I'm probably going to be in the regular season right now."

There's the evolving roles of Jordan Crawford and Terrence Williams.

On whether they'll sign Terrence Williams to another 10-day deal, Doc Rivers says, "I think so."

#Celtics coach Doc Rivers: Jordan Crawford, right now, his conscious is too good. Trying to be a ball-mover ... We want him to be a scorer.

Doc likes TWill as a point guard and Crawford filling the wild card/scorer role left by Leandro Barbosa. Regardless of what they're "roles" might be on this team, what's great about their additions is that they're ballers. I've tried to make this distinction in the past, but there has been a somewhat different attitude to how Danny has approached free agency in the summer and during the season. In the past, Ainge opted for more "know your role" type guys like Ryan Hollins, Sean Williams, and Greg Stiemsma last season, but lately, he and Doc have been looking for guys that are just players. Including the late off-season addition of Barbosa, management has looked for guys that are good at everything, but not necessarily great at anything. Now, with a higher emphasis on ball movement, guys like Williams and Crawford aren't just relegated to being distributors and shooters. They'll be responsible for everything.

And finally, D.J. White is officially a Celtic.

D.J. White is officially a member of the Celtics. He just spoke with the media and will practice today. He'll wear No. 12.

There's word that the Celtics won't be looking at any buyout candidates, but it sounds like recently released Lou Amundson might be in the picture. White has some familiarity already with some of the Celtics and he's been with the team since they played in Portland. He's on a ten-day and my best guess is that he'll stick with the team for the rest of the year. Even if Amundson is in the picture, White has been steadily playing competitive basketball in China for the last several months where as Amundson could barely get off the bench in Minnesota. White's younger with more upside and just seems like the perfect fit in that baby bruiser role that we've been missing for several seasons now.
