You got Carter, Bosh, Mighty mouse (Damon Stoudamire), Jose Calderon & Alvin Williams.
1) Vince Carter
2) Chris Bosh
3) Kyle Lowry
4) Jose Calderon
5) Alvin Williams + Damon Stoudamire
My reason: If Kyle Lowry helps to advance the Raptors to the second round, a good argument could be made that he might deserve to leapfrog over Bosh as the second greatest Raptor ever (Something that Bosh never was able to do). However being that this is the only season Kyle Lowry shine's maybe we have to wait another season or two before we can come up with a more precise rankings and whether he should leapfrog Bosh in the standings as the greatest Raptor.
