Hmmmm...well, that's several points that are difficult to refute. Would you please quit doing that?
Haha....again, you state several solid points. But there's almost unlimited variables involved here I think. For example, how could a recent Super Bowl HC be a truly
massive HC failure for NU? Maybe only Clownahan can answer that?
Also, Frank's an old man now (how old is he? 70 or more?) and has been for some time. While there certainly are exceptions but bright, successful HC's are usually somewhere under 50 years old. Sure, that's an excuse, I know. But c'mon.....Frank in his 60s & 70s at a program that's never won anything that I can recall.....well, I think that's a little unfair. I dare say that Alabama or Nebraska is a lot, lot different than Ohio in many ways.
Anyways, your points are valid and I don't have a good answer. To a degree however, most College football coaches don't shine to bright when they're 60 or 70 + years old.
