Totally fine, give your reasons. But your personal attacks are an embarrassment to your parents and your family. Go Blue.”Underwood led the Wolverines to a 9-4 season last year, 7-2 in the Big Ten, as a true freshman. Whittingham won his first game as Wolverines head coach on a Hail Mary against the Broncos on September 5, a game that sparked controversy nationwide as officials added one second to a clock that appeared to run out.Poggi led Michigan to wins against Central Michigan and Nebraska as interim coach in 2025 but lost to the Texas Longhorns in the Citrus Bowl.Whittingham’s Wolverines are now 2-0 on the season with UTEP on the schedule for September 19 followed by the team’s Big Ten opener September 26 against No. 21 Iowa. Whittingham and Underwood endured plenty of criticism leading up to the Oklahoma game, but it appears firmly in the rearview mirror now.Related: Oklahoma HC Eric Morris jokingly ponders retirement after beating OregonRelated: Oklahoma’s John Mateer doesn’t hold back on brutal performance in Michigan loss
