To me Sullivan is the one who is probably most declining. Against really big, physical DTs like the Bears had he was getting pushed back in the pocket all night. And collectively they certainly were beaten badly all night as a group. But I don't think there are any alarm bells going off about their OL. It's still a very strong unit. Detroit, Kansas City, even going back to Green Bay- those are all very good fronts/pass rushing groups.
But also credit the Rams for addressing the future of the OL in April's draft (Noteboom, Allen) and my guess is they will more next April as well.
