I've seen some people dinging him for ball security in yesterday's game, but it looked a lot like the Detroit player lowered his helmet and caught Goff in the back of the head while also hitting his arm. Not only would nearly every QB in the league fumbled with a hit like that, isn't that supposed to be a penalty? He also took 2 shots to the knees , only the second one was called.
Stafford dove to the ground like he was shot with a cannon ball after he was shoved by Suh and got a roughing penalty.
