I think TP is great. But he's a finesse RB. And he can run between the tackles, I never said he can't. Most of these guys can, at least a little.
But what I and others are saying is that he, or any of them, aren't power runners. They aren't built to take the pounding (and deliver the blows when necessary) on a consistent basis. To be that runner that can routinely move the pile, to get that tough inside yardage and/or TD when your down close. To act like there isn't a difference in runners and running styles is just being disingenuous.
