Most teams with our injury list would be playing backup LBs as Safeties and hoping to hang on.
Now, the notion that I've got some brilliant idea to make it better is obviously stupid. The coaches are paid tons of cash because they're light years better at fixing this than I am.
However, small things should be noted. In particular, when was the last time rushing 3 achieved the desired effect? Our defense is built on aggression, and the longer you give a Big 12 offense, the more you're likely to suffer a long completion. Always bring at least four, keep the OL guessing, and bring 5 or more on 3rd and more than 6.
