This section of the Athletic article is insightful:
As the season progressed there were clear philosophical differences between what Fickell and Longo wanted, with Fickell repeatedly stressing the need to lean on the offensive line and run game more. And while Longo’s offense emphasized the run, he failed to mesh his concepts with Wisconsin’s roster. Perhaps his most notable quote occurred when pressed about the lack of results earlier this season when he said: “I’m here to please coach Fickell.”
Longo did not respond to a cell phone request for comment this week from The Athletic.
