Raw speed is the one thing that can't be taught. That said, we used to have Ted Ginn, a guy who had wheels for days. But, man oh man would Ginn drop the easiest of catches. Still, super fast guy with cannon arm QB was the ideal pairing.
T-Mac isn't going to pull away like Ginn but he does all the other things well, especially for a rookie. It's looking like a great pick so far although we really needed to draft someone like him earlier.
