This thread is showing our short-term memory is on the fritz. The hype of Frost being hired at Nebraska was several notches higher than Rhule's hiring. The guy took over a 0-12 UCF team and went 13-0 in 22 months. The 2017 AAC was excellent; Memphis was undefeated in non-UCF regular season games. That was the last really good USF team (the 3,215th instance of terrible timing for Illinois non-conference scheduling). He was returning home with immense helium. He was going to bring the Oregon offense to a conference division stuck in the 20th century!
Rhule could prove he's the goods but there's no bigger failure than Frost's flop as UN coach because the hype, (short) track record, and returning home story hit peak levels.
