Russ had what has become his 'normal'--a good game statistically, but not a good game actually.
First and foremost, he was terrible trying to command his offense at the line. He was a net-negative as on-field leader for his team. In addition to delay of games, he was legitimately confusing his own team pre-play.
Second, he actually threw more than one terrible ball when he actually tried to do what he's known for and air it out. Our curse of not being able to hold onto gift interceptions the past couple of years seems to have continued (at least into game 1).
Russ did well in the screen game (which he had, traditionally, been terrible at before, so that might be on us) and he actually took some of the check downs that he refused to look at for most of his last few years.
But he also greatly benefitted from facing a young defensive secondary that got undisciplined a few times and either completely dropped assignments or let receivers get in behind them on plays where they should have stayed over the top. Those are miscues that the tape from this game will help our guys but Russ can't count on that gift from every team he faces.
