Texas A&M vs. Alabama: Tide has knocked the lights out of mobile QBs

The only quarterback so far this season who has been able to put up positive rushing yards against Alabama is Michigan's Denard Robinson. For No. 15 Texas A&M, any hopes of knocking off the unbeaten Crimson Tide rests on Johnny Manziel becoming the second to do that.

Throughout the year, Manziel has touched up opposing defenses to the tune of 102 yards on the ground per game. That makes him 26th overall in the nation and fourth-best among quarterbacks, just behind Robinson. It's a big part of why the Aggies are 11th-best in the nation in rushing with 251.3 yards per game. But in top-ranked Alabama, the Aggies will face a team that has excelled at shutting down quarterbacks who scramble and sprint for yards.

Against Michigan, the Crimson Tide put a beating on Robinson – who has nearly 1,000 yards rushing on the season – and kept him to 27 yards on 10 carries. For the season, Alabama has kept all rushers to a measly two yards a tote. Only Louisiana State, which picked up 139 yards last Saturday, has broken the century mark against the Crimson Tide – but it took the Tigers 49 carries to get there.

Manziel will put Alabama's defense to the test Saturday afternoon in Tuscaloosa. Kickoff is set for 2:30 p.m.
