Some of you must have stopped watching after the 4-4 start because when McDermott was kicked out to LT and Gauthier/Gall entered the lineup the OL improved dramatically.
This....
St. Louis played very well in the final 5 games too
Did you watch the bowl game? They struggled with west virginia d-line.
It's all relative. Part of the reality is that fans have warped expectations for what an OL is supposed to be able to do despite facing talent on the other side. There are a handful of teams in College Football that have OLs that actually regularly get push on running plays. Our OL was subpar last year, for sure. But, I remember so many of the same complaints by our fans specifically regarding "getting push" in the run game when our OL consisted of Seantrel Henderson (NFL starter), Ereck Flowers (NFL starter), Brandon Linder (NFL starter), Harland Gunn (3 year starter whose strength was run blocking) and Shane McDermott (3-year starter, all-conference player).
That OL was definitely better than our OL last year, but the same complaints were made regularly regarding "getting push" run blocking. I think adjusted expectations may be needed.
