I remember an interview he did after winning some assistant coach award (national award) when he was at Oregon. I thought to myself then that he would possibly/quite probably be a HC for us in the future. He came off well, seemed to have the charisma and seeming coaching chops to become a very good HC. But there is usually more to the story, as we found out.
His couple of years at UCF were anti-jinxed. He inherited a ton of talent, and his laid back attitude worked for that G5 school, and the state they were located in. There was no real pressure there, and Frost has proven he is a bad coach when there is pressure. I feel a lot of things simply went UCF's way, where a lot of things also contrastingly did not go Frost's way at NU. Some of it is luck of the draw, at least at times.
HC of the Huskers is by default a pressure cooker. He just isn't/wasn't built for it. It probably didn't help that he was our QB for our last championship team, as that made the expectations, and thus the pressure, even more intense.
I do think the way things started out with the lightening-gate game, etc, all just snowballed and he wasn't ready for any of it. But the large majority of the issue was that Frost himself was not cut out for the expectations. He coached scared and his assistants for the most part were yes-men. It became obvious too quickly, that there were issues with trust and accountability with our Frost coached Huskers. He just shit the bed in so many ways as HC for us.
Is he an asshole? I don't know him personally, he came after my time at NU was done. but have heard is can be an arrogant ass. I think we saw that play out pretty clearly the previous 5 years. Confidence is good, but too much and for the wrong reasons is not. I do know T.O. was high on him during his high school years (he was obviously a very talented in-state high school player). When Frost chose Stanford, T.O. wasn't happy about it. Once Frost transferred to NU from Stanford, things were already lined up where we were a juggernaut of a program. But Frost still was our QB for a championship season anc was a good QB for our style of play that T.O. utilized.
People talk shit about Frazier a lot - and some of it is deserved. I knew Tommie really well. He had his faults, but he was also uber-talented and also fit to a T what T.O. needed/wanted in a QB. Tommie was a great QB and player for us, even with his faults/deficencies. I bring this up to correlate to Frost, as he also fit what T.O. needed/wanted in a QB at the time, and we were at the top of the heap of college football so both players excelled as our teams then were great overall anyway. But was Tommie a good coach? No. Was he a great player? Yes. Being a great player does not always make one a good coach.
In any case, the correlation mostly ends there, as I think Frost does have a good offensive mind overall. But as a HC and team leader of a blue-blood, he wasn't cut out for it, and likely never will be. Some people just cannot handle the pressure, and multitude of resonsibilities and leadership qualties needed for a pressure-cooker blue blood program that was starving to get back to prominence.
