230 is better than 205-210 under Grantham. Spikes at 6-3 265 ish would have played DT under Grantham, maybe nose tackle.
it is hard to find a big guy that can run sideline to sideline. It's just as hard to find a little fast guy who can hit hard enough to take on a 220 lb running back or a 300 lb offensive guard.
So it brings me back to my original point that continuing to play these Big 12 style defenses is the problem. It hasn't even worked at Alabama the last few years. they have not been dominant. Even they have had trouble finding the dudes strong enough to play inside and fast enough to run to the sideline. Just switch back to 3 linebackers, a big Mike and two fast lighter outside backers, except on third and long or vs a pass happy team.
