I could be wrong, but I think the Cavs want a trade exception from Haywood's contract, but they can only get a trade exception by trading him to a team that is under the cap for at least Haywood's contract.
However, I don't think we have enough space to do this.
Oh, and the idea of literally giving up on one of the best shooting and passing big men in the NBA blows my mind. That was Stevens' first pick with Ainge. He is a hard worker and continues to develop parts of his game.
I would consider trading him if it meant we could sign a star, but Holmes wasn't ever the fourth best player on our summer league team.
