I think there needs to be a couple of points made. Not that I disagree with the idea of this argument or the tone of it, but. . .
1. Spread offenses make life difficult. When you put athlete on athlete out in space and try to get the ball out of the QBs hand in three seconds, your D-line can get neutralized pretty quick. That doesn't excuse the poor tackling we've seen so far this season or the quitters attitude when faced with adversity. It also doesn't explain our weak a$$ run defense, or how we're getting gashed by an FCS team.
2. Football continues to get pussified. In an age where people fear breathing on a quarterback will give him a concussion, sowing a mean, nasty defense will reap a plentiful harvest of penalty yards. Not that we don't do that already under Pelini, but some of the viciousness we associate with Nebraska teams of yore probably wouldn't fly anymore. That does not, however, negate your point about mentality or respect. This team doesn't respect itself, and it shouldn't. They play like crap on defense and the offense is not much better in setting a tone (yet).
I really don't know what the answer is for Nebraska. I think we have talent, but it's not doing us much good on the big stage. We'll see how this season progresses. I think a new coordinator on the defensive side of the ball--somebody experienced--to counterbalance Bo would be a solid start. JP is a waste of salary and time. Beyond that, we've had so many conversations for so long about how to 'fix' this team that the only plausible answer I see remaining is some kind of coaching change.
I expect Pelini to win quite a few games yet this season. I also expect him to drop one or two more winnable ones. If we find ourselves in primetime again (not all that likely), modern history has told me to be very pessimistic about or chances of even surviving a game with our heads held high, much less winning it.
