I understand your point but like I said above, our defender didn't even hit him, the way he fell to the ground caused the separation. Something like that could happen to any QB
IIRC, I think the first time I remember him reaching for the shoulder was on that bogus Ellis penalty; late hit out of bounds. Something wasn't right in his shoulder and he probably came back too early. But if the guy is fully cleared by the best doc known to athletes, what are you going to do?
