The last two head coaches we've hired have been all or nothing in terms of offense/defense. Wilson was all offense, Allen is all defense. Allen is now looking for a "head coach of the offense" because he doesn't trust himself with having anything to do with that side of the ball. Did Bill Mallory, Bo Schembechler, The Bear or others have such a strong knowledge of one side of the ball, or were they more well rounded?? I just don't remember those coaches knowing all or nothing...help me out, please. FWIW, I knew Wilson didn't know defense after a few attempts to answer questions from the media regarding his swiss cheese unit.
