You'll get no argument from me with respect to the coaching issue. IF Havs isn't injured, then he's clearly regressed this season as opposing D-linemen are simply running right by him. But then again, he was never considered the most athletic O-lineman out there.
Regardless, I still believe that a linemen like Battle deserves an opportunity to get something on tape for the next coaching staff to evaluate. We clearly know what GRob and Havs are (or aren't) capable of during regular season game action.
Not so much with Battle. Let's see what he has to offer.
