I don't really think pass rush is a priority on the line with our scheme, as odd as it seems.
It really seems like they are relied on more just to hold the line against the run, which they are typically reliable in doing. I mean, we run a four-man front with three dudes starting (and two of the three main backups) who are much more like DTs than DEs in size and athleticism. And then we have a fourth guy in Ziemba who basically plays as a stand-up linebacker type half the time.
It would be great if they could get more pressure, sure, but I don't think it is a massive priority as long as they can hold blocks and help with the run game, which they've done well. I mean, we led the conference in sacks this year, so it isn't like we typically were in dire need of QB pressure other than today; we even got to Fields with the offensive line Ohio State has quite often.
