Despite his desire to play a bigger role — which may not be possible on the Celtics — Big Baby insists that he’d like to remain in Green and White. The Boston Herald reports: “Glen Davis certainly picked an angst-ridden summer to become an unrestricted free agent, and not just because it’s a CBA year. For the first time in a young career marked by some great postseason moments, Davis melted into the floorboards last spring. He averaged 4.9 points on 39 percent shooting in nine playoff games, including four points on 31.8 percent shooting in the Eastern Conference semifinal loss against Miami. Davis found himself, once again, on the wrong side of coach Doc Rivers’ ledger, and never recovered. But most general managers stick to the longer view. And once the rush begins to sign free agents for the 2011-12 season, Davis will be in demand … Neither Davis nor Rivers publicly admit to having a problem, though Ainge said he wants the men to talk out their oft-emotional differences if they are to spend another season together. If that opportunity arises, anyway. Davis, at least, asserts that he wants to return. ‘Man, I do,’ Davis said yesterday. ‘Do you know how much I’ve grown and learned with those guys? I want to keep playing with Ray (Allen) and Paul (Pierce) until they leave.’ Too much is unknown, though. In Ainge’s quest to find a capable big man this summer, Davis is probably the Celtics’ best chip in a sign-and-trade deal.”
