Honestly, Rigo hasn't fought anyone of merit. That guy looked like he wasn't even a local gym champ. That isn't a knock on Rigo's merit, but that BS wouldn't/shouldn't trouble any top level fighter with top level speed, reflexes, instinct, etc...
Rigo and Gamboa do it to every fighter they face. I wouldn't call it a feint either. But a feint can work against anybody.
