Staying pretty 30,000 foot response, and if you just stick with the Colorado game, I don't know if I would come up with anything others couldn't. But maybe...
1 - Outcoached
2 - We were the worse conditioned team in the 4th quarter and overtime
3 - Get Kade Warner back please, someone that can be a threat as an outside WR. People claiming missing Stanley Morgan wouldn't hurt are being proven wrong
4 - Our OL is an issue, we gave up 6 sacks to a terrible defense
5 - Adrian Martinez decision making
All of those things are something that I think can be fixed so I feel comfortable saying they need to get better, yet not panicking that they can't.
