If you look at stats, the sample size is way too small. If you've watched every game he's played (for the Leafs) like I have, you realize just how solid he is. He's always in the right place. His anticipation and positioning is top notch. He's got a calmness about him that Anderson doesn't have. Anderson seems to have to make more flashy, erratic saves, but Campbell never looks flashy because he's always in the right position.
You can tell by watching him that he's starter material. The only question is whether he can stay healthy.
