I would say it is accurate to a certain extent (his clock management and in-game decisions are atrocious at times), BUT you have to take into account KF's gameplan and his style.
He relies heavily on execution and I think he would get that in the NFL more than he ever will at Iowa.
Obviously better talent is going to help ANY gameplan, but KF's gameplan actually relies on it to be successful.
I think with KF it could go either way if he coached at the NFL... Either he would be extremely successful and would fit well there... or it would be an utter disaster. I don't think there really is a middle-ground.
Even our best offensive player (McNutt) has troubles executing at the level NFL players do on a regular basis... i.e.: Making the simple catches.
That isn't a knock on McNutt, because I think he is extremely talented and gifted. It has more to do with the lack of focus. When it is an easy catch that he KNOWS he can make, he starts to think about what he is going to do AFTER the catch BEFORE he actually makes it... which we all know leads to dropped balls a lot of the time.
I have been skeptical of KF's coaching ability at Iowa the past 2 years, but I think a lot of things get overlooked that KF does a hell of a job at. He is coaching student athletes and I think he does a damn good job of helping these kids grow as men... which is what a lot of "successful" coaches can't seem to do. He not only puts good players into the NFL, but he puts good MEN/Human-beings into the NFL and at the college level... you have to respect that.
On the other hand... I wonder how he would be able to handle all of the headcases that plague NFL teams. If he thought DJK was tough to handle... Try handling someone like T.O. or OchoCinco or Randy Moss and those types of players.
It would be interesting, but I wouldn't be so quick to write KF off and say he hasn't done anything to prove himself as a good coach.
