You're right...Brown has done an awful job, and personally I think he's an overrated coach. I made this point once before that unlike the true elite coaches, he doesn't know how to make the most of the talent he's given. He has one style, one philosophy, and he only knows how to do things that one way. He's been way too shifty with the lineups and the rotations, which has been ridiculous. As for the defense, I think the players earlier in the year actually asked for a simplification of the D....how can a team like that be expected to play a zone defense which involves more strategy and understanding.
The main issue here is that Isiah has never had a plan with this team...he claims to have one, and then he changes direction with the bat of an eye. And yeah, LB may have asked for Francis as part of that "list" he gave Isiah, but I'm sure he didn't say he wanted both Francis AND Marbury in the same backcourt and have Jamal Crawford coming off the bench...that just makes no sense, and it's up to Isiah to use his own common sense to figure that out and make the right moves. LB was brought here to coach, and he can give his opinions on moves, but that final decision is Isiah's...he's the moron that doesn't seem to know what he's doing.
