Not saying you're necessarily wrong, but I have a couple thoughts that may or may not make you feel better

:
- RE: surviving off dropped or missed passes, some of this is credit to the defense. They took it to Purdue yesterday, creating tight throwing windows and disrupting routes. Obviously there were a few passes that Purdue could have (and should have) caught, but that's just part of the game and it's pretty clear Nebraska's D disrupted their mojo and I think it contributed to Purdue's overall offensive funk.
- RE: blitz and coverage decisions, I don't know what the analytics say, but I trust Tony White lol. His philosophy appears to be to want to apply pressure on 3rd and short situations to force quick passes. It's hard to get a good pass rush with just 3-4 guys. And the longer you give a QB, the more likely they are to find a guy. White wants to force that decision quickly apparently and force the QB/WR to make a play fast. He probably likes his chances.
