As anti-WR as I am, I am pro-Calvin. I am pretty sure he'll be a stud, and might be TO with better hands and no attitude. That's pretty awesome.
I don't think he's the deep threat Moss was, which is why I think it'll be tough for him to make that kind of impact as a rookie.
So yeah, I guess I agree, I don't know if he plays that fast. There's fast, and then there's Moss, Troy Williamson, Tedd Ginn fast. He ain't that fast. But he's more than fast enough.
