Michigan Wolverines quarterback Denard Robinson has been Notre Dame Fighting Irish football's Kryptonite for the past three years.
But Saturday night, the Irish found a way to counteract the once-weakening force known as "Shoelace" in their 13-6 victory over Michigan at Notre Dame Stadium.
The win, which broke a three-year losing streak to the Wolverines, will surely put Notre Dame into the national title discussion. Sitting at 4-0, the Irish have the opportunity to jump into the Top 10 after entering this week at No. 11.
For No. 18 Michigan, the loss exposed a struggling defense and inconsistent offense.The Wolverines will likely drop a handful of spots in the AP Top 25.
While it wasn't the barnburner college football that fans have grown accustomed to in the past three years, Saturday's game was certainly entertaining.
There was no doubt which was the better team, but there are questions regarding both the Irish and Wolverines.
