Been watching college football since I was 3. I'm 42 now. I've never seen a bad tackling defense become a good tackling defense in one year. It's usually endemic of coaching, but I'm giving them a pass for now because it hasn't been a glaring issue until right now. But I really don't have a lot of hope this defense will get much better as the year goes along.
The one thing they do have in their favor is they won't face Franklin again. But I believe Illinois has a QB who can run, and we know Oregon and Stanford do. They better figure out how to contain the edge or this season's going to get turned on its head before it gets started.
