Trev's primary resource is this thread, as it should be. We're brilliant.
Not that it really matters, but I think we should keep in mind that Frost was much more than a fan choice back in 2017. He was probably the hottest coaching candidate as that season went along, and likely the biggest reason Nebraska got him was because of his ties to the state. Florida and Tennessee were also pushing him hard and just about every college football analyst/pundit thought that Nebraska had hit an absolute home run with that hire.
Naturally, there were some questions about how it would all work out and what it would look like, but I think it is an unfair disservice to a lot of people who worked hard to make that hire happen if we characterize it as a "fan choice." There were a lot of teams that wanted Frost and there were a lot of reasons to like him as a candidate.
