Since Butler left, you need a better go to scorer in MIA that can create and with better handles. RJ can fill that gap.

Raptors get better defensively with slightly better 3pt shooting despite worse handle and scoring ability. Wiggins fits better with the Raptors system despite the drop in offense. Raptors get the more favorable first rounder next year... So a chance to go up a bit in the draft because they are getting an older player and they are losing some self created offense.
