We just haven't gotten to see much of our LBs yet because no one runs against us and our scheme has rendered the LBs basically useless in pass coverage.
And here's where I see the glass as half-full on defense also - Banker has his safeties play much closer to the line than Bo did. Banker wants to see his safeties in to help fill running lanes.
So in the games that really matter for us in our division, I feel much more confident in our ability to stop the run. Stave and Stave's receivers, for example, are NOWHERE close to what Kaaya is/has. Even Connor Cook probably isn't as accurate as Kaaya. Meaning that in the games that matter, we're going to have the personnel and FINALLY the scheme to actually not get blown out against Wisconsin. And we should even be very competitive against MSU as well.
All of this in theory should translate into much better Big 10 defensive play than what we've seen against Wisconsin when we've played them these last few years. Scheme-wise, I think our defense has a lot of potential to actually win our division this year.
