If Jones keeps Machida up and Machida wakes up and starts to complain Jones haters could call it an early stoppage, bad officiating, and demand an immediate rematch. Machida fell on his face because he chose not to tap, it's like saying oh Mir should have stopped right before Nog's arm started to break. Jones job was to lock the submission on, Machida's job was to admit that it was a successful submission.
Regardless, this, promos, pales in comparison to the assault cases.
I still say Diaz stalking Riggs in the hospital(when he has an IV in) and urinal and calling for a fight with another guys genitals are out id say covers most unsportsmanlike and disrespectful act. You are talking about serious premeditation and constant action for what an hour maybe two.
