A few things can be speculated about as to why Frost has struggled. At Central Florida, he went from 0-12 to 13-0 in two seasons - the first time that had been accomplished in the history of college football. He probably showed up to Lincoln a little overconfident and set in his ways. Frost was still quite green as a head coach in 2018. The Husker job was probably still a bit too big for him. We can point to a few different factors that have contributed, but there is one major blunder Frost made when he was hired that made this job a lot more difficult.
Bringing his entire staff with him from UCF was honorable and showed loyalty, but it was also naïve and short-sighted on his part. It proved to be detrimental. There's a reason why it was referenced so many times when he did it. That's because it's just not done. There are coaches who jump from one prominent Power Five school to another and don't take everyone with them. So you can understand why I was initially critical of Frost bringing an entire Group of Five staff with him to the Big Ten, one of the pillar conferences in college football.
