As Alan12 said, there was improvement but it was somewhat marginal. I could say that it was unlikely to be a complete night and day transformation of the Penning we saw last week into a Saints version of Joe Thomas. If the general sense was that he was someone who needed reps to refine technique, become more consistent and develop better awareness, then that's a job of several months (and years), rather than a week. But, small improvements are better than no improvements or getting even worse - so that's the very slim silver lining.
As a whole, the Oline has been disappointing. I can think of reasons and context as to why. But in the end, it's a results business and in terms of contribution to the ultimate result of winning games (2-0, Yay!!), the Oline is making that harder, rather than easier. I believe it should get better, but the level of confidence isn't incredibly high right now. I'm sure we'll look better against poorer defensive units, but in a vacuum, this OL is at best middle of the pack in the NFL. "No, they're the worst of all time!!!" I can already hear some of you say in reactionary and hyperbolic fury. I suggest casting your eyes on the OL's we just faced or around the league and middle of the pack is probably about right.
