"I think this Where: Michi- one will pose a gan Stadium real challenge TV/Radio: to our defense ESPN because they're like three offens- es in one," said Michigan defensive coordinator Greg Mattison. Nebraska features a dual-threat quarterback in sophomore Taylor Martinez, a power running back in senior Rex Burkhead, and an offen- sive playbook full ofnooks and cran- nies the Wolverines have never seen before. "They will run the power, they'll run the lead play, they'll run the toss, toss-(isolation), and then they'll get into some of the option read stuff," said Michigan coach Brady Hoke. Put those all together, and that adds up to a stiff task for the Michi- gan defense come Saturday. "They're a power attack," Mat- tison said. "(Burkhead) is a really good downhill runner. They go from that to being able to be an option attack with (Martinez). It makes the defense have to be sound in all phases." Possibly the most difficult task for the Wolverines (4-2, 8-2) will be stopping the option - Michigan's ability to contain the outside has been an area of concern, though it has improved over the last sev- eral games. Mattison noted that the focus on gap integrity and contain- ing the edge heading into Saturday will be "huge." "Whenever you have an option team, responsibility and doing your job is critical," he said. "You have to be really disciplined playing a game like this." While the Wolverines have improved in defending the outside, the Cornhuskers have improved running the option, too - Martinez said they spend a set period of time every day to solely practice the play. Burkhead said Martinez has been "tremendous" at running the option and has continued to improve throughout the season. Martinez credited his improvement to experi- ence. "Every time we do an option, I get better and better at it," Martinez said. "Every game I'll keep getting better." But Michigan can't get too caught up in focusing on defending against the option. Nebraska offensive coor- dinator Tim Beck seems to always have something new up his sleeve. "He's like the witch doctor," said Nebraska coach Bo Pelini. "You don't know what he's going to do." On top of running several differ- ent offensive schemes, Beck likes to keep a very up-tempo offense, often trying to catch the opposing defense off guard. "That's a concern," Mattison said. "Any time a team tempos you, you have to find out how mature your defense is. You have to be a very disciplined defense, and you have to be a tough-minded defense to know that you're going to get the call at the spur of the moment." But the Wolverines have the personnel to successfully com- bat Nebraska's up-tempo offense. Seniors Ryan Van Bergen and Mike Martin mentioned this week that they've become comfortable calling GENE PUSKAR/AP Senior Rex Burkhead is the main cog as the running back in Nebraska's offense. audibles at the line when they deem fit, and Mattison has full confidence in them to do so. "You can't load up and play the power because you may be getting optioned," Mattison said. "You can't go in there with an idea of being a finesse or assignment totally or you're going to get the power run right at you." It's a test that Martin and Van Bergen say they're ready for - the two senior leaders have already had success in calling plays at the line this year. Against Illinois last week, Van Bergen called an audible at the line that resulted in a sack for the 288-pound defensive end. The Wolverines enter Saturday's con- test ranked second in the Big Ten in scoring defense, giving up an aver- age of just 15.5 points per game, and first in red zone defense, stopping opponents from scoring two-thirds of the time. And recently, Van Bergen went so far as to say that Michigan has the best defensive line not only inthe Big Ten, but also in the country. When asked about Van Bergen's comment, Hoke was straightforward. "We have two games left to see that, right?" he said. "I know one thing - if you're gonna talk the talk, you better walk the walk." 8 1 FootballSaturday - November 19, 2011
