I don't like letting AB call the shots here anymore than you do but the dude can refuse to go to a team and if that happens (like it did with buffalo) then that blows up the trade.Still you don't have to give in to him. Something like a pick, less than a #1, is not valuable enough IMO, to hand him what he wants.
This isn't 1971 where a coach walks in, tells the player he is traded and he has 12 hours to pack up and get on a plane.. doesn't work this way anymore..
