Cormier has a point in that what happened to him really wasn't "that" bad, it was embarrassing yes but you see ass whoopings like the one punk took happen in MMA gyms if you workout at a decent one.
Once Gall got him down he could have worked for a joint and likely have broken it before Punk could have tapped.
