re: What is the root cause why O failed ?

It was a house of cards to begin with. His success was always going to depend 100% on his ability, or lack thereof, to both recruit at an extraordinary level and hire and retain elite coordinators. He was fortunate to inherit Dave Aranda and we paid him what would be head coach money at most places to keep him. He struck gold in hiring Brady - his role in hiring Brady has been argued about ad nauseum, not worth getting into. He did a good job of recruiting early on. But once Aranda left and the mask came off it became abundantly clear he didn’t have what it takes to lead and sustain an elite college football program. He doesn’t have the acumen or knowledge or temperament to command the respect necessary to keep a steady pipeline of elite coordinators, and be failed. Oh and he also couldn’t stop chasing arse
