You do understand that if simply having Carazzo press down causes Adams' shoulder to pop, then Judd was in fact pulling vigorously and far in excess of that required to simply 'hold the arm out of the way'?
That's simply not how the body works mate. You've got it wrong. There needn't have been any pulling from Judd to have caused the shoulder to twist or pop. He needed only to have applied force required to hold the arm stable while Carrots then pushed the shoulder into the turf twisting it beyond normal ROM.
