Can you imagine a backfield with Johnson and Barkley in it. Ho would defenses ever defend that? Both are terrific runners and both can catch the ball. Even if you run them out one at a time and kept rotating them to keep them fresh, defenses would have a nightmare of a time with it. Either one could line in the slot while the other one is set in the back and defenses would have to account for both of them. The possibilities are almost endless. In this case a good game manager would be all you need at QB. Actually thinking about this would make Thesmel cream himself.
