While MMA is clearly his strong suit, McGregor did show that he can be formidable in a boxing ring, capable of landing punches against one of the best defensive fighters ever. He absorbed big shots and put up a respectful fight until his stamina waned and Mayweather pounced in the later rounds. He might not have won the fight, but McGregor earned the respect of some skeptics from the boxing world - and certainly performed enough well to elicit more boxing suitors.
