My money would be on arkansas. I think our defensive faults this season come more down to playing a high powered offense and not just a mobile qb. our most impressive defensive wins were against teams with decent/consistent offenses iowa/msu but nothing close to teams like wiscy arkansas and I guess michigan b/c played lights out. It seems like they tend to go into meltdown mode when they get put on their heels. But who knows a month is alot of time to prepare.
