Nebraska is not good, but...
Nebraska has a higher winning % than Tennessee in the 1960's, 1970's, 1980's, 1990's, 2000's, 2010's. Has won more games than UT every decade for going on 70 years.
With that said, neither job is appealing to me if I'm a coach. Two programs who used to be great and can't get it right. Still have very high standards and expectations. Hard to see the upside from the POV of a coach.
And that's why I believe many see Scott Frost as the best option. Going through coaches left and right catches up. If I'm Matt Campbell, F that. I would not blame him even a little bit if he totally looked away from a hypothetical offer from Nebraska. He's at Iowa State who traditionally doesn't have a good football program with much lower standards/expectations, and he has it going on right now. Energizes the entire fanbase, where as our fanbase at Nebraska puts a tremendous amount of pressure on any coach.
Scott Frost is the best option because he wants to be at Nebraska first of all and also he knows more than anyone about the culture. Makes the most sense.
