While the obvious choice is Porter, that could be determined by our draft. But I am one of those who believes we will draft Quinn so I don't think our first rounder will play this year. Given that, I'll have to say Porter. If we draft Ginn, I'll say him because of his special teams performance.
EDIT: By the way, you left of Cory Schlesinger. He's going to do wonders for our running game.
