ND has multiple years of blue chip QB recruits crashing and burning and or not working out at QB - Christ, Golson, Hendrix, Zaire, Kid who transferred to Cinci, Wimbush, Jurkovich, Davis and now increasingly looking like Buchner.
It’s also kinda crazy that 2 of the best 3 QB’s during that period didn’t receive much coaching from the ND staff before taking over the team (Kizer and Coan) and the best of the bunch statistically (Book) basically plateaued his first season. That’s grounds to can everyone that has been involved in the evaluation and development process at that position.
Clemson on the other hand has had good to great QB play the majority of the time Debo has been the coach.
