Pittman started when Anthony was suspended, then he got benched for Turiaf (that should give you some sense on either how raw he is or how bad he is).
Anthony is one dimensional. he's not a pick and roll player (which we would need with this team) nor can he shoot.
take those things away and think about the fact Bonner wouldn't last with Spoelstra (or Riley pulling the strings) on the defensive end. right now they're winning with a G-G-F-F-F starting lineup, why would they kill that chemistry to bring in a guy who hasn't done squat in the post season and can't play his position on both sides? Bonner isn't going anywhere, we need to accept that (even if it takes a whole bottle of vodka).
