Of the 4 mistakes at ND (Faust, Davie, Ty and Charlie) Charlie was far and away the worst. He could get offensive skill to ND, but every other aspect of the program was a dumpster fire. His records of 3-9, 6-6, 6-6 would have continued into perpetuity. Probably gotten worse because of his personality.
Charlie was the worst combination of traits. Cocky, an insufferable d-bag and totally incompetent. His only purpose in football should have been to be a valet for Bill Parcells & Bill Belichick. Other than that he was literally more useless than tits on a bull.
