The Lions have 14 pass attempts and 30 run attempts and most of the pass attempts have been screens at the line of scrimmage. He took one shot down the field and seemed to grab his back afterwards.
I would put it on Campbell if Goff is too injured to throw. When they are throwing, it's just screens. Remarkably they would still be winning this game without a missed extra point.
It was a screen. That's the only receiver available on a screen call. He should have fired it into the ground. Lets not get carried away. Matthew Stafford made a much more egregious mistake last week.
Benching Goff would just be punishment. I don't know the team would respond any differently to a worse QB. Maybe you rig a COVID test so he's ineligible to play.
