Royce Freeman was explosive and Nebraska didn't really have an answer for him last season until he was hurt. Even then, their backup RB had quite a bit of success. This is where I'm really hopeful the defensive side shores things up. Oregon will be a tough game this year, no matter what anyone says about their record last year. Once a team has a few things go against them, it's not uncommon to have the wheels fall off and a lack of effort. We've seen that here at Nebraska.
They have a dynamic QB and a Heisman-caliber RB. Granted, their defensive woes will likely not be "fixed" over an off-season, but I expect this to be another close game.
