Think we could get Chicago's first round pick this year for him?
They are going to need to fill that void.
He's essentially a free agent at the end of this year and the Bulls aren't going to pay him much to keep him considering he'd probably force them to pay the repeater tax. He's not the guy who will take the Bulls over the top. Basically, no, they're not going to surrender a 2014 1st rounder for a rental of Jordan Crawford when that doesn't appreciably increase their chances of winning a championship.
A team like Miami or San Antonio might be more willing to do so, but we have no idea how well the Bulls will finish this year, so their pick is probably going to be more valuable.
