Roster talk: Is this it?

The Celtics practice Thursday at the TD Garden.BOSTON -- The 2011-12 NBA season tips off in 10 days and Celtics president of basketball operations Danny Ainge admitted Thursday that there's potential that there will be no further additions to the Boston roster.

"I don’t know if there’s anything I need to do, but there’s some things that we’re still working on," said Ainge. "I think that this roster is what it’s going to be. That's always the case when the things that we would like to do are usually tough to pull off. We’re planning on this roster for now."

Pressed on if size was a concern for the center-light Celtics, Ainge dismissed the notion, telling reporters to look at the size on the floor behind them. Celtics coach Doc Rivers admitted he'd like a little more size at the center spot, but sounded content to ride with what he's got.

"I like this team," he said. "I like our bench. Obviously, we have flaws, we’d love to grow a little bit, but we’re not. I think they’re done. Their growth spurts are all over with at this point, at least upward... I like our team. We’re always going to look to improve if we can. Right now this is who we are."

While Ainge said he hadn't observed enough practice time to know if any of the training camp invites -- Greg Stiemsma, Gilbert Brown, Jamal Sampson, or Michael Sweetney -- had distinguished themselves, Rivers suggested none had, but offered high praise for 6-foot-11 Stiemsma, a strong candidate to fill out the roster given his size.

"I do like Stiemsma," said Rivers. "I can't even say his name. But I do like him a lot. He hasn’t really separated himself or anything, but I like some of the things he can do. I think we have to convince him what he can do. He’s actually a terrific shooter from the elbows -- he’s not a post player at all. And he’s a terrific shot-blocker, he blocks everything. We gotta get him comfortable shooting when he’s open. It happens even with veterans, when you play with Kevin [Garnett] and Ray [Allen] and Paul [Pierce] on the floor, you almost feel like you’re not worthy to take an open shot. I think he’s in that phase right now."

Later Rivers added on Stiemsma, "I think he has an excellent shot at sticking around."
