Calling nebraska a team with no potential to be great is stupid. Any team can be better than they are, especially the perennially undetperforming Huskers. They are in the weaker half of the second worst Power 5 conference. With their schedule this year and last, they should have lost 2 games at most.
They pay enough to get a top 20 coach and top 20 coordinators, but consistently performs worse than the top 20.
I hope they go with someone young and fresh. Scott Frost would be cool, as he is Nebraska-bred and has had a lot of success as a coordinator in the PAC12. If he could pair it with a competent DC, Nebraska could get back to a perennial top 15 ranking.
To say that Nebraska's ship has sailed is stupid, I think our best years (outside of the 90's, which no team will emulate ever again) are in front of us.
