Devin Gardner proved that he deserves to be the Michigan Wolverines' starting quarterback, starting next year, of course.
Or while Denard Robinson remains injured, whichever happens first.
Gardner accounted for six touchdowns (three rushing, three passing) Saturday during Michigan's 42-17 pummeling of the Iowa Hawkeyes at The Big House in Ann Arbor.
The junior threw for a career-high 314 yards while headling a Michigan offense that scored at will.
Robinson showed that he could do well in a limited role, rushing for 98 yards while Gardner spread the ball around to receivers Jeremy Gallon (5-133) and Roy Roundtree (5-83, TD), who accounted for more than 200 yards receiving and a score.
Iowa's defense was no match for Michigan, and its offense struggled mightily. Not having receivers Keenan Davis and Kevonte Martin-Manley contribute certainly hindered the Hawkeyes' point production.
It was a resounding triumph for Michigan (8-3, 6-1), which still has its eyes on a Big Ten Legends Division title, but undisciplined mistakes and questionable personnel decisions raised questions that need answers.
Why were starters left in during the fourth quarter? What if Gardner fumbled that ball after scrambling from the goal line?
Feel free to leave comments about those topics, as well as the others we'll cover in the Senior Day edition of "what we learned."
