You are truly turning a blind eye if you honestly believe Scott Frost gave it his all at NU and it just didn't work out. His total disregard for his job and marriage are very well documented here and elsewhere. As far as the marriage part, I could give two squirts what he does in his personal life, but when you consistently show up to coach this team after a hard night of binge drinking, which ultimately screwed up this program even more than when he got here, then I do have a right to be pissed.
He was fooled by his own success at UCF and thought it'd be a simple plug and play here. His huge initial contract went to his head and he immediately started acting like a co-ed again. When it started to turn south on him he just called it quits and let the program flounder.
I don't care what you call it, but he didn't earn his pay at NU at all. He took advantage of his long leash with his drinking buddy Moos and should be ashamed to call himself a Husker.
