I posted a an article awhile back from ESPN.com which basically pointed out how so many college coaches make it to the NFL thinking they are the latest "genuises" and will take the NFL by storm.
Usually, they go through a struggle until they realize that, for all their college genuis, the NFL is different in many ways. The offensive plays and schemes in college usually don't work in the NFL without some alteration.
Spurrier will find this to be true in the coming year or so, and if he's as good as they say, he'll adjust. THEN, and only then, will I expect his teams to flourish.
