I said it before the season when everyone was thinking this team would go 8-4 or even 9-3. This is the same team as last year, with even less depth on Defense. That team went 5-7 so addition of a new coach does not add 3-4 wins a year unless it is a VERY special year. A new coach with some better coaching techniques may add 1 or 2 wins but he still needs the athletes to play and these are the same athletes as last year's disappointing team. Everyone drank the kool-aid but now it looks as though the kool-aid well ran dry.
Now people can point out the Oregon St. win of USC or the Ole Miss win over Florida and say anything can happen and Nebraska can win against Mizzou or Tech or OU, etc. But in 4 1/2 years we have not seen this team beat someone that they were not supposed to beat, in fact they routinely have lost to teams they should have beat. It's just not in Nebraska's makeup right now. So sure it could happen but I don't see it happening. Next year maybe, but not this year. Patience is needed and they will be better in the long run.
People need to curb their expectations because those who have huge expectations for a team that just does not have the talent to do so will be the most disappointed and the ones with the least amount of patience for a new coaching staff.
