How do you explain the turnaround at UCF? Would be interested in getting your take...
Turner Gill turned Buffalo around quickly. Dan Hawkins turned Boise State around quickly. Darrell Hazell turned Kent State around quickly. Tim Beckman turned Toledo around quickly. Jim McElwain turned CSU around quickly. Charlie Strong turned around Louisville quickly. Rich Rod turned around West Virginia quickly.
Success at a lower level does not guarantee success in a major conference. Power 5 football is a different animal. You're going against much better coaches. You're dealing with different types of players/recruits who have bigger egos. You have more non-coaching responsibilities, more media and boosters you have to deal with.
If you look at the top coaches right now, many of them were not previously head-coaches at lower-level schools - Dabo, Day, Riley, Orgeron, Smart, Whittingham, Mullen, Chryst - none of them were mid-major coaches. It's all about being able to recruit, develop, hire good assistants, and manage egos.
