As for Toronto being bad, you have seen it and you know their weird schemes and personnel concepts. Their big wing concept and no true bigs is getting them killed on either 3 (if they drop) or paint (if they dont).
Btw did you know they actually only have 1 guy in their entire roster (Rookie Christian Koloko) who is even taller than 6"9?
