I realize that Boston won't have much room for signing free agents, but there's gotta be one or two serviceable bigs whom the Celtics can sign on the cheap -- to play a few minutes a game to spell JO and KG, and to take up space and grab a few rebounds. Somebody on here mentioned Gadzuric, and it seems he'd fill the bill: 6-11, 240, averages about 4.5 points and 4.5 rebounds a game for his career. There always seems to be plenty of scrubs like him in the league, but for some reason Boston's had a hard time landing these guys -- you know, unspectacular-but-solid 5-minute-a-game guys to take up some space.
