Penning is a very good to borderline elite run blocker. Yes he does need to get better in pass-pro but this was his 1st yr healthy and with a real OL coach. I think he gets better and becomes a very good RT.
Making any accurate assessment of our OL is next to impossible due to the injuries that the OL had. An OL is all about playing as a unit and except for the 1st 2 games we were never really a unit
