...I look for Riley to go and former Nebraska QB Scott Frost to take over.
Possible. I have little doubt that Nebraska will offer Frost, but I don't know that Frost will take it. Nebraska can offer more money, but the average duration of a Nebraska coach is only 3-5 years these days. Scott is a young coach, and I'm not sure that 3-5 years of great pay, and then back on the coaching carousel will be attractive to him. If he likes Orlando, most likely he can stay there as long as he wants.
We'll just have to see how it plays out. In the meantime, this is a great addition for Ohio.
