Part of the issue with the offense and the line is that these are very young units overall and the conditions on the field on Saturday were not great so I think those are important factors one has to take into consideration when evluating offensive performance from Saturday.
Going into the game on Saturday, I really expected it to be a 21-17, 17-14 kind of game and I did not expect the offense to click as well as it did when it did so given that we scored 30 and held them to 9, I have to say that I'm legitemately thrilled with how we did overall, especially with how phenomenal the special teams and defense were on Saturday.
Yes, the tepid pace of the offense in the 2nd half is a concern, but I think that's mainly due to lack of experience of a young unit, conditions on the field, and probably also Campbell rotating guys in and out so I don't think it's actually all that good of an idicator of a bad offense.
I think that they were just playing it safe with a young QB and a lead. Makes sense to not put too much pressure on them when the game was already out of reach. It was definitely frustrating seeing so many 3 and outs, but they got the win and didn't have to risk anything to do it. That early pick 6 from Cooper was huge and took all the pressure off the offense.
