ANN ARBOR, Mich. — Michigan is moving on from its controversial victory in Week 1, and Bryce Underwood is still its starting quarterback — at least for now.Most of America was fixated on the decision by Big Ten replay officials to put one second on the clock at the end of the game, paving the way for Underwood’s Hail Mary that allowed No. 16 Michigan to escape with a 13-12 victory Saturday night against Western Michigan. Michigan coach Kyle Whittingham is more concerned with fixing the mistakes that put the Wolverines at the mercy of a replay.“I’m assuming they got it right,” Whittingham said Monday. “They looked at it, and their technology that they have is very advanced, I guess. I think everyone is fairly satisfied with the explanation. I am.”Whittingham wasn’t as satisfied with Michigan’s offense. The Wolverines managed only 276 yards against Western Michigan, including 170 through the air from Underwood, who completed 12 of 22 passes, with an interception and a 47-yard touchdown pass to JJ Buchanan.Underwood remains Michigan’s starting quarterback as the Wolverines prepare for Saturday’s showdown against No. 10 Oklahoma in Ann Arbor. While Whittingham continues to back Underwood, he acknowledged Monday that Underwood will be playing for his job if the results don’t improve.“He’s our QB right now,” Whittingham said. “It’s not something that’s infinite. At some point we’ve got to turn a corner, and we’ve got to see improvement.”Whittingham was effusive with his praise for Underwood during preseason camp, but Underwood’s public performances tell a different story. Underwood was 3-for-9 passing in Michigan’s spring game and struggled with many of the same issues Saturday.“It is unfortunate and disappointing, because we see him every day and he’s been very sharp all through fall camp,” Whittingham said. “I don’t have a great explanation right now, other than we hope to see improvement between Game 1 and Game 2.”Michigan’s backup quarterback is freshman Tommy Carr, the brother of Notre Dame quarterback CJ Carr and the grandson of former Michigan coach Lloyd Carr. Carr held off Colorado State transfer Brayden Fowler-Nicolosi to win the backup job and has been taking about 20 percent of Michigan’s reps with the starters in practice, with Underwood taking the other 80 percent.Whittingham did not indicate Michigan was contemplating a quarterback change before Saturday’s game against the Sooners, but such a move is on the table if Underwood continues to struggle.“I don’t want to panic,” Whittingham said. “I don’t want to get ahead of ourselves. (Underwood) is a big-time talent with his arm talent and his ability to run. We’re just going to stay the course for right now, but again, there does come a time for everybody where we’ve got to look at an alternative if you’re not getting what you need.”
