I think Nebraska is going to have to get worse before they can get better. They are built to run the option, and pass 5-10 times a game -- an offensive philosophy that no "high-profile" coach endorses. Its going to take at least 3-4 years of recruiting to get the personell needed to really fit another system. Which is about the same time its going to take for the next head coach to wear out his welcome and get canned.
Have they tried to pry Mike Beamer from Virginia Tech? I think he might be a good fit, but I dunno if he'd leave.
