I can't see cuban/nelson letting dirk go...........unless there is a sign and trade for a a dwade/lebron type. and I would say that is wishful thinking. dirk means too much to dallas and is too good of a player for them to just let him walk. they learned that lesson when steve walked....and at that point they didn't realize what they were losing. with dirk you are talking about a proven franchise player(unlike steve when he left).
