Don't see how the Jazz can demand a player. Boozer has already agreed to join the Bulls, giving the Jazz a trade exception via S&T is just doing the Jazz a favour. He's not in a Bosh situation where he's trying to get a extra year from the deal.
Well I figured they might be doing the Bulls a favor by giving them more cap space. They're going to need it with Lebron going to Miami. Johnson would have been a nice pick-up and I would have taken Gibson too.
Not sure it was much of a favor though. They got a pick out of it and I doubt the Jazz ever use the trade exception or the other two they have.
