I think Mora just blew it on a few transfers and some players didn't develop like he hoped. It happens. Talent evaluation and roster management are probably going to be the two most important skills for a college football Head Coach in the NIL/Transfer Portal era.
As much as I thought Edsall was wildly overrated as a coach, and I didn't even like Edsall 1.0, he was one of the best talent evaluators I have seen in college football in the last 20 years. His ability to build a competitive program in a BCS conference with 2 and 3 star recruits in the 2000's looks even more impressive in hindsight. Too bad he was so annoying, bullheaded, and unwilling to adapt. He would have been a very effective coach in the NIL/Transfer Portal era if he had just been willing to change.
