Mess was forced to add Coach K's playbook, the pistol stuff to his offense, and it didn't go so well. I heard at the Iowa vs ISU game that the playbook was way too big, and one big mess at that point. It also didn't lead to a cohesive offensive staff at ISU, and led to some bad blood. This is obvious with the Mess and Pope firings, and Bliel will be moving on of his own accord.
I am kind of surprised that Coach K might be getting the OC job. I figured that he would also be fired (didn't hear he would or anything, just kind of assumed it), as he was partially responsible for the whole situation. Maybe Rhoads sees it differently, or I just only heard one side of things. Either way if K moves into the OC spot, my one big question is why not make that move last year? Why try to make Mess run and implement someone else's offense? Clonedude has some nice posts in the other OC thread that make some sense as to why that might be.
That is basically what I know. I heard some other eye openers as well, but really aren't pertinent to this situation.
