The Skins' offense couldn't run the ball nor stop the run when they needed to. Joe Barry should have changed it up early to have Norman match up with Antonio Brown after the first score.
Sean McVay should have adapted when Couins wasn't getting pressured with just three or four rushers. He should have taken more time to survey the field and let his receivers find soft spots in the zone.
If the coaches don't adapt, this is going to be an extremely long season.
