Every college football season brings certain expectations for big-time programs. New recruits, promising transfers and flashy coaching hires excite fan bases -- and sometimes those expectations hit. We knew the 2021 Georgia Bulldogs' defense had a chance to be legendary. It was, and it led the team to a national championship. We also expected this season's Ohio State Buckeyes to be great offensively and the Michigan Wolverines to be dominant in the run game.
But some teams do fall well short of expectations, leaving us wondering why much-hyped units can't get it done with stars at multiple positions and once-intriguing schemes in place. Which early disappointments stand out this season in college football? We zeroed in on four struggling units. What is broken for each of the four -- e.g., Oklahoma's lackluster defense -- and how it can be fixed? Plus, what are the 2023 NFL draft implications for each unit's struggles?
