Record was never really going to matter.
This team was 4-8 last season. They came in to the year with the second hardest schedule in the entire country with most of the teams being 10 win units from the year before. Troy is 4-1. Wisconsin is 5-1. Michigan is 5-1. Colorado is still undefeated.
The only 'bad' team they've lost to so far was Purdue and they had just come off of blowing out a ranked BC team. Nebraska has been in every game except the Michigan debacle and probably should have won most of them. They just make stupid mistakes - easily one of the most penalized teams in the country.
First year with a new coach in a new scheme against a strong schedule with depth issues everywhere. It's been well stated at this point that Riley's staff practically sabotaged the program with their policies, namely the lack of weight training and lackluster practicing.
95% of Nebraska fans are still fully behind him. Especially since you can see his scheme working at some points. Three of the loses came with the offense firing on all cylinders. It'll just take more time.
