I'm tempted to say they made a good effort, but with the caveat that they BLEW IT IN THE FOURTH QUARTER, WHEN IT MATTERED. Look at Jamaal Charles' rushing statistics and tell me that the defense did a great job. The guy hit three homeruns in the fourth quarter. There were many missed tackles that helped facilitate his near-300 yard rushing day.
This was still a huge improvement over what we've been seeing for the last month and a half, but seriously folks, is this Nebraska football? We have to blitz on every down in order to get ANY pressure on the QB or contain the runs up the middle. The front seven should be able to hold their own on run containment and pass rush without bringing the whole house.
I wouldnt put the 4th qtr entirely on the players. Cosgrove didnt make any adjustments to his defensive scheme..
