I agree with this (Elway, not the Cylon).
Elway was a special player and athlete that brought a ton to the table that no other QB had until then. I think the main difference between him and Josh is that Josh is a better and more effective runner. But it's hard to say if Elway would be that way if he played now...back then, I imagine most QBs didn't want to run as much because of the terrible beating they would take.
