I was thinking he'd have a big game for two reasons:
1. The Bulls stink.
2. If he was really serious about wanting a trade to Chicago but the Bulls weren't giving Petrie any good offers, what beeter way oto say "get yout butt on the phone!" than to dump 30 on you?
Anyways, it's probably just the #1, but that would be quite a story if it was #2.
