If they decide to keep him, their best option may be to send him to play for their D-League affiliate. This would be a huge insult to many players who have started consecutive years in this league, and especially a slap in the face to a starter who should arguably be in his prime.
It could go 1 of 2 ways:
1) Ideal: Biedrins would probably be the best center in the entire D-League. This means he would dominate. This means he would gain confidence through his dominance. After 4 weeks of destroying semi-pros, he gets recalled and his confidence carries over to NBA games on a consistent basis. He finds the fire again. Remember those summers playing in Latvia? Remember how confidently he spoke of a "new Andris Biedrins" all those years ago? Maybe this situation mirrors those past experiences, and positively effects his consistency.
2) Disaster: Andris completely loses confidence and his feelings are hurt. He plays even worse, in a worse league. He makes the gag reel on ESPN. He loses all value, and we can no longer trade him.
I realize this is a highly unlikely situation, given the fact that he's the only real center on the team, and Mark Jackson probably would protest the move of even happening in the first place.
But what do you guys think?
