Do you have any idea how long it takes to develop offensive linemen? Hint: longer than any other position on a football team.
Unfortunately, that means you're probably not gonna see much improvement from the OL by the end of this year. On the other hand, there are zero seniors on the OL 2-deep. Don't be surprised if these same players look very different by the time they're done with their careers at Nebraska.
You're missing something: right now, Frost doesn't really even have the luxury of playing guys other than the ones he recruited on offense. Spielman and a couple linemen, that's basically all that's left of the Riley era on offense. Frost's guys are still freshmen and sophomores! Yeah, some underclassmen can be significant contributors. But do you know what happens when 3/4 of your offense is underclassmen and transfers with just a few months in the system? You're looking at it.
We did have 6-9 last year...
