I am 1,000% sure McNabb/Don Mac would have absolutely turned that record upside down. Did you watch those guys? I ask sincerely. I'd say 900% Graves and Philcox get to 6 wins. Norley/Mason, toss up but i'd take my chances.
I'm blaming Dungey for the injuries b/c he's jumping over guys and running like a fullback. I saw this with Rob Konrad too who was supremely talented but never played a full season (and he was a fullback, not a qb).
A great QB can win games single handidly in college football. If we're gonna use your metrics we should discount every single great qb who had played in a tough conference with a system, great RB, etc.
At some point we need to see wins from the qb to annoint "great". That's me anyway.
