I think Perkins would accept a backup role behind Sheed, and if not, I think Gortat can give us almost the same type of game without the outside scoring Sheed brings, which we don't NEED (but would always like).
AI is best when he's on a bad team with him as the only option and guys that want to play defense. Best lineup he played on: Eric Snow, Aaron McKie, Iverson, Mutombo, etc. All defense guys, very little scoring options outside of him, NO FIT HERE.
Pachulia I don't like either. I don't think he brings half of the mobility, defense, or rebounding Gortat would bring with a chance to play, and I couldn't stand looking at those huge ugly lips making that "who, me?" face whenver ANYTHING happens.
