It's hard to argue that.
I don't have an advance degree in this stuff, but I think what we are trying to establish the run and then work off play action.
What's happening, though, is teams aren't afraid of that. They are charging down hill and attacking our backfield. At that point, we are just sitting ducks back there.
I realize this may all work on a napkin, but at some point, if the fish aren't biting, you need different bait.
