Why this is the perfect trade for Boston: Elite offensive center: Boston acquires Nikola Vučević, an All-Star center who provides scoring in the low post and rebounding, a chronic weakness for the team in the postseason.

Immediate improvement: Vučević is an established player who fits right into the title race.

For the Bulls: Rebuilding Chicago acquires a high-level defensive and shooting guard (White) for their future core, while getting rid of a veteran center.
