I'm not nearly as captivated with Pruitt as some on this board and it's not just because I don't think he's that good. In fact, I think that he might be option #2 in terms of who to cut, after POB, if this team adds two vets. Here's why:
1) Doc isn't going to play him in the playoffs. You can potentially critique Doc for this (but I wouldn't); however, like it or not, Pruitt isn't going to get time in the playoffs unless someone gets hurt. There's 27 games left in the regular season and he still hasn't gotten regular rotation play. With Tony Allen back and Doc most likely looking to see what Cassell can do, there aren't going to be minutes for Pruitt. Even if there are, I can't see Doc going with Pruitt in a playoff rotation over House and Allen, who have both played in the playoffs before.
2) He may not even be back next year. The Celtics have 10 players under contract next year. The only 5 not under contract are Pruitt (team option), House (player option), and Davis, Powe, and Cassell (unrestricted). The C's are most likely going to want to add a vet or two and they're going to have a first round pick. Add to that House likely exercising his player option and the C's trying to bring back at least one of Powe and Davis, and I don't see where Pruitt fits in next year.
3) He's not that good. He really isn't. I hear some people saying he's better than Delonte West in this thread. And to that I have to say, are you crazy? Before West got hurt he was starting on a championship contender. If Pruitt was so good, he'd actually be able to crack our rotation and beat out the likes of Eddie House and Tony Allen. Pruitt's upside is to be Delonte West, which means he'd be a borderline starter/good bench player. But that's his upside, that's hardly what's likely to happen. There's about as good of a chance of that happening as there is of him being out of the league altogether in a few years.
So, I don't see how he helps in the short term and I don't know if he's even going to be around next year, so I don't think it's really worth trying to integrate him into the rotation at this point.
