I think you are over valuing the significance of a bye this time of year. If you have people who are banged up and need recovery time, it helps. however you can't overhaul your entire Offense or Defense at this point. You might do what Coach Brohm did at Purdue and insert three new starters in the OL to get new blood on the field and shake people up. However, that isn't going to work every time and especially in the OL with people who haven't played together before. You might re arrange your depth chart to get a better look at some of the Players you were planning to red shirt who have progressed in practice and use the 4 Game Red Shirt Rule to get them on the field. But looking at Nebraska, they were lucky to beat Northwestern two weeks ago on a last second field goal from a 3rd String Walk on kicker, and last week they were steam rolled by Minnesota. You don't get all of that corrected in a bye week.
