Unless a guy simply can't go, no one should be sitting. And the notion that JT & JB are playing too many minutes is ludicrous. Brown isn't even averaging 35 minutes. Michael Jordan averaged 38-40 for the bulk of his career. If anything, Stevens is too easy on his players.
We're on the edge of the play in game, when getting to a 4 or 5 seed is extremely important. Brad would be a fool to save someone for the playoffs, when saving them means the difference in playing Atlanta or New York in the first round instead of Milwaukee or New Jersey.
I believe in Brad, I think he's a great coach. I also believe he has grossly mismanaged this team, once again, and a team that should be contending with the top 3 seeds is instead fighting for its playoff life.
