The idea that "This (ie. Demps up the middle, pitch to Demps, etc.) is 75% of the Offense 'til Demps gets hurt and/or we get slaughtered..." is the source of the frustration and sinking feeling that is building in so many guts in Gatorland--mine included.
As others have noted, we are NOT short of alternatives at running back; indeed, we've got a kind of ideal mix of styles and change-of-pace. Demps is a beast, but he can't carry that kind of load--and given the alternatives, it's not only foolish but unnecessary.
Don't want to blame Addazio? Fine with me--JUST GET IT FIXED! Blame is beside the point in ANY event. There's a ton of talent on that team--including a QB with a rocket-arm and a bunch of fast young receivers who need game-experience, just waiting to get out there and prove themselves.
The vertical passing game is a big part of how this offense was supposed to function, ultimately. Is it the coaches' opinion that this team has NO RECEIVERS ready to run the routes or catch the long ball yet? If so, how and when will any of them be ready?
