Jourdan Lewis is one of a number of defensive stars for the Michigan Wolverines, and he has been virtually impenetrable for opposing quarterbacks this season.
Pro Football Focus, an analytics-based football site that grades players on a play-by-play basis, tweeted out a pretty crazy stat about the season that Lewis is having. According to PFF, Lewis has allowed just seven receiving yards this year. Add in the interception he registered against Wisconsin, and quarterbacks have a 0.0 QB rating throwing against him this season.
Opposing quarterbacks have not fared much better against the Michigan defense as a whole. The Wolverines are surrendering just 10.3 points per game this season. The full-game QBRs for opposing quarterbacks are better than 0.0, but not by much. Every quarterback that has thrown at least 10 passes against Michigan this season:
-Sefo Liufau, Colorado: 60.6
-Dru Brown, Hawaii: 45.1
-Justin Holman, UCF: 24.6
-Trace McSorley, Penn State: 12.3
-Alex Hornibrook, Wisconsin: 7.6
-Ikaika Woolsey, Hawaii: 1.5
-Zach Allen, Rutgers: 1.5
-Nick Patti, UCF: 1.0
With average QBR set at 50, only one player—Colorado's Liufau—has had a decent game against the Wolverines. The defense, led by Lewis, Heisman contender Jabrill Peppers, Channing Stribling, and others, will have Jim Harbaugh's team firmly in College Football Playoff talks all season.
