According to Chris Sheridan, his draft expert on his site Joe Kotoch said the basis for trading up would be #5 and GS 17' 1st-round pick for #2. He added the Jazz don't wanna give up a young player (Favors, Kanter, Burke, Burks) to move up which is contradicting to other reports. He said the Bucks want future picks if they are going to trade down.
I think that's a no-brainer. My faith that the Warriors implode by '16-'17 is waning a bit. Maybe it shouldn't, a lot can happen between now and then.
