Those sound like some really good ideas, at least worth trying, but not sure they would tinker with that during the season. This is the kind of stuff they should have figured out in the off season. If I was coaching for my job though, I'd try to make some changes now rather than later, which might not come.
You are exactly right.
If I felt (unless a behind the doors agreement said otherwise) my job could be on the line without improvements in the OL, I would certainly make moderate changes a week at a time to try to improve that position.
That being the case, at that point SF doesn't even have to say anything to Trev, because he is showing Alberts through his actions that he is willing to change in order to try to keep his job.
Staying with the status quo in terms of OL personnel, he is essentially showing that he may not have any answers, and that's not what Alberts wants to see.
And then theoretically, in games when this OL continues to get its lunch ate, it further magnifies the weakness of the OL coach and by extension the inability to manage a position group by SF.
I'm not on a crusade here, I just see what should be obvious to anyone. This OL is bad, bad. We are relying on a stout defense to carry this entire team. That's great until we lose an essential player or two to injury or Covid.
I haven't said anything about the Husker D. I think Eric is doing a good job and has a ways to go. He/we fans, benefitted by the return of the Super Seniors and they are making the most of it.
My concern is NU's inability to pressure/sack the QB. I've seen #31 the transfer run up the back of his own defensive lineman time after time. So calling on him to blitz has been a no go.
Sorry for being so long.
