The Illinois DL is not real deep, they may go 5 deep on the front 3, but they also moved a starting OLineman to Dline after Bielema arrived. If Nebraska moved Benhart or Jurgens to Dline we would be concerned about DLine depth. Running the ball will help, but rushing the passer play after play takes as much out of a DLineman, physically, as getting pounded does. Teams with no depth need to get worn out physically, then mentally. Nebraska's Oline will probably be improved, but it isn't quite to the point of dominating a team up front yet.
In my opinion, I want to see to see a 50/50 or 55/45 mix of run/ pass over the 3 quarters then a steady diet of Stepp in the 4th to either salt the game away.
