Green did turn to look for the ball. He turned while the RB player was juggling it in the endzone, which gave him no chance to break up the INT. It was pretty perfect.
Obviously something went wrong. I'll go back and watch the play again, but I know GB blitzed. It looked like the oline was pass blocking, but I'll have to watch the other WRs to see if they were running routes, or acting like it was a run too.
The simplest explanation is that Green misheard the play call. Kind of fluke-y way to lose a game, but not the end of the world.
Going forward, I'm way, way, way more worried about the run defense than I am AJ Green. This team isn't winning poop giving up five yards a carry.
