Most Huskers might completely disagree with me, but I agree with what you're saying. Nearly all the calls against us were correct, it's just that roughing the passer that is absolute garbage.
I think the Cotton penalties were crap, but that's how it always is called. There should have obviously been a penalty on you as well, but that usually won't get called. Yeah, the ref did what he had to do (once he saw Cotton kicking) but my question is HOW could he not see him being groped? If all he saw was Cotton kicking, then he made the right call based on what he saw; however, he should have been able to see more.
Other than that, I won't complain about the calls against us. There were multiple holdings missed against you guys, and that's what a lot of us are going to complain about. It's not necessarily that our number of penalties was too high, it's just that yours was too low.
