I agree with what everyone is saying about needing to see what comes next. The way I see it, these are some factors that need to go into really evaluating what this win means.
1) What we do the rest of the way. If we tank the rest of the way, then it was a fun moment in another medicore (2-6 or 3-5) conference season. A nice win, and a sign that we are on the right track for sure, but nothing earth shattering. If we win at least 2 more games before the bowl game, then we have had our first .500 or better B1G season in a long time, and this was a huge win that really got the ball rolling.
2) What Nebraska was the rest of the way. It was huge for Kill to collect his first ranked opponent. However, I would really rather the metric for beating a ranked opponent be based on where they are ranked at the end of the year, not when we play them. We have a limited sample set for looking at Nebraska against quality competition this year. If Nebraska tanks, this could be like Illinois in 2008, an upset that didn't end up being as significant as we thought it was at the time. Conversely, if Nebraska wins out, then we managed to beat a really good Nebraska team, and that is huge.
3) Rivalry. I know not everyone thinks like I do, but I know some people do. It is more special when we beat a rival. Wisconsin, Iowa, Michigan, in that order. If you had to ask me if I could choose between being a 1-loss national champion with a loss to Wisconsin, or a national runner up with the axe in our trophy, I honestly don't know what I say. Games for axes, pigs, and jugs take on extra special meaning, so the next big milestone for Kill is going to be getting his hands on those trophies.
I really hope no one reads this as me trying to rain on anyone's parade. I was ecstatic about the win, and hugging my buddies in the stands after Nelson's last touchdown then running on down to the field was some of the most fun I have had at Gopher football ever. We should be very pleased and proud of this win. However, just to keep perspective, all that we have clinched at this point is another trip to a bowl game and at least a 2-6 B1G record. The team can't such sit on this accomplishment, this group really could be something special, and the biggest thing they can do to underscore the importance of this win is to ride the momentum to see how high they can fly.
