I don't see much of a comparison. The gap of physical ability potential between Fitz and DWill is much, much greater than the gap between Madkin and Wyatt. Madkin also won a SEC West championship prior to the year of the comeback in 1999.
Madkin and Wyatt were both game managers. Our D, Oline, and backs were sick. We only passed when we had to. We had very limited options at wide receiver. KP was elite.
In Mullen's offense (at least the way it is currently run), our QB is not asked to be a game manager. He is asked to be THE game changer. Our Oline and backs are trash and we have a couple of solid receivers plus one that is elite.
The bigger picture is that our QB is not the problem. We are comparing our QB play to Dak...to some extent I think Dan is too. We are putting way too much of a load on them because we have no other option. We are too weak at OL and RB.
