Deng's really a small forward though, isn't he? They were really lacking a shooter, anyway. Jefferson's not a bad shooter, but he's no Kyle Korver. The guy they REALLY needed was Mike Miller, but alas.
I could see Cleveland making a move, but that would be dumb on their part. Jefferson's the classic kind of player that Cleveland always brought in to "complement" LeBron - guys that were OK but not true #2 running mates. Now that LeBron's gone, they need to blow that thing up.
