Will Bradley be Rondo's primary fill-in?

Of the many questions looming over the new-look Boston Celtics this season, none may be as pressing as this: Who fills in at point guard until Rajon Rondo returns from a torn ACL?

Celtics president of basketball operations Danny Ainge recently hinted in a radio interview that Rondo may not play until December, and on Wednesday he explained more to The Boston Globe.

“He seems to be in a really good place, emotionally, mentally,” Ainge said of Rondo, “and now we’re just trying to get the physical part done -- and he’s got a ways to go.”

The question has always been which of the Celtics many guards -- Avery Bradley, Jordan Crawford, Courtney Lee, MarShon Brooks and Phil Pressey -- would get the nod in Rondo's absence. However, based on the praise coach Brad Stevens gave Bradley on Thursday, we have to believe he could be the odds-on favorite as long as he's mentally ready to play.

"... I don’t think there’s any doubt that Avery has elite ability in a lot of ways as a point guard," Stevens said, per masslive.com. "And when I say that, he’s an elite defender at the point guard position, he’s an elite athlete at the point guard position. And I think he’s a guy that has gotten better, I think he’s a guy that’s gotten more confidence, and I think he’s excited about the challenge if Rondo is out.”

Last week, A. Sherrod Blakely of CSNNE.com reported that Bradley may miss the start of training camp as he continues to cope and grieve the recent loss of his mother, who passed away at age 46 on Sept. 10.
