There are many reasons why Ohio State has dominated Michigan football for much of the last two decades, but the biggest has been the lopsided play at quarterback.
At one time, it was Michigan that had the advantage at quarterback. From around the time that Jim Harbaugh was the Wolverines starter, all the way up through Chad Henne, just about every UM starting quarterback got drafted. Scott Dreisbach even got picked in the draft after being a backup.
But since the era of Jim Tressel and really since the days of Troy Smith, the Buckeyes have had much better players at quarterback and it has made all the difference in college football’s fiercest rivalry.
