re: Jamal Sampson and Skinner...I never have understood why a player is even on a team, if the coach is NEVER going to use him. I can think of plenty of instances this year when it obviously wasn't working out for Brad, and Adelman either continues to play him, or subs in a shorter guy like Corliss or SAR at center. WHY? What harm would it do to play Sampson or Skinner in some real, actual game time? That's the only way to truly judge a player's potential contributions to the team, and it's the only way a young player will EVER get better.
Not to get off topic though...
Name three centers better than Brad in the league, and tell me how we could possibly fathom getting them without tearing this team apart all over again? It's a weak position league-wide. I don't think Brad has much to worry about...for now.
It comes down to using all your weapons that you have available. Certain matchups are not suitable for Miller, and that's when we should be sending in one of our ACTUAL backup centers to give him a breather.
