ALLEN PARK, Mich. -- The idea first sprouted in a meeting at the end of 2016, part of a sales pitch from Bret Bielema to his star center, Frank Ragnow. The former Arkansas coach and his most talented pupil had become close over the past few months and now, they were sitting in his office. Bielema was explaining the reasons Ragnow should consider coming back to school for one more season.
