The run games lack of success is not surprising when you consider the struggles of the passing game. Plus people forget this offensive line never played a snap together until week one. Ravens have a great run defense. I think a game like this will definitely help the run game as Peyton proved that no, he is not washed up and yes, he can still shit all over a good passing defense.
It's not just Peypey that looks exceptionally better in shotgun, even the run game benefits greatly, averaging almost a yard per carry higher so far this year shotgun vs under center. It's because teams fear the pass. Put that same 3WR/1TE/1RB or 2WR/2TE/1RB personnel on the field with him under center and the defense changes coverage and pressure. He just does not look comfortable at all under center.
A lot of that is terrible line play, which will get better as time goes on. But I am happy they have struggled mightily on offense yet still won two very tough games against two good opponents. Bodes well for potential success when firing on all cylinders.
