Nam Y. Huh/AP SOUTH BEND, Ind. When Notre Dame and Wisconsin play at Soldier Field on the last Saturday in September, it will mark the first game between the schools in 57 years. That alone should make for tasty viewing, but now there’s the Jack Coan Factor, too. The Badgers’ starting quarterback for 18 games in 2018-19, Coan lost his job to redshirt freshman Graham Mertz after having season-ending surgery on his right foot in early October. Two weeks after entering the transfer portal Dec. 20, Coan landed at Notre Dame as a graduate transfer just as the record-setting Ian Book headed off to pursue a professional career.
