I actually made a thread about this awhile ago but you're right on all points. One thing I'd like to point out is that I've worked as an on field trainer for football and a couple of things I used to ask with a shoulder injury was "Can you roll your shoulders?" and "Does how does it feel when you let your arms dangle?" Well, Hopkins rolled his shoulders when he tried to show Kellerman the injury without any problem. He also held his shoulder down by his side and not in a sling position. Gravity is a ***** and tweaks the AC bad. The fact that he let his arm dangle shows me he wasn't badly hurt.
Actually, he is a surgeon. It's been pretty well documented that he went through medical school. And he said he thought Hopkins was faking, so....
