the problem with Fisher is offense? He is bad at that part of the game and good at most of the rest. A's and B's elsewhere, but an F brings the GPA down to a C. Hence the 7-9 records.
And that includes the whole thing. Developing players, developing a scheme, preparing for an opponent, etc.
and you see many players with talent not living up to expectations. I think you see the same trend with QBs. Most of them underachieve. At some point you have to evaluate what is the real cause and effect. and a logical conclusion is Fisher is the Cause of so many offensive players being so slow on developing.
