fryowa, i just happened to watch Roethlisberger in the bowl game he played as a SR and i hoped like hell the Steelers would pick him up. the reason? i saw him on a scramble from side to side and throw a strike, on the run, for a touchdown. Big Ben didn't used to be a statue and was quite agile. he's lost his knees and he's pushing 40. Stanley isn't nearly the scrambler Ben was, even if, Stanley has more straight line speed.
some of his highlights in college. the last play is similar to what i was describing above.
