re: How did our O-line get so bad?

Guys - it's coaching.

We are signing enough highly ranked guys. We've signed enough guys in general. Aside from this past 2021 class, we were signing 4 or 5 each year.

Just check out the linked thread.

These guys aren't panning out. Whether it's our evaluation of signed players... or our scheme, our OLine coaching or our strength and conditioning program. We've got way more misses than we have hits on the offensive line.
