I think we're being too harsh on AJ, as well as going overboard with the word "quit."

Should AJ have shoved the ref to the ground in obvious anger after the "wave-off"? AJ was clearly buzzed. He was leaning back into the corner, but looking at the ref. It's the ref's job to decide whether the fighter is apt to continue. Quitting, IMO, would've been if AJ had shaken his head no.... or voiced as much to the ref.
