No, he was commenting on Mayweather coming forward and stalking him, which is considered the Mexican style.
Usually Mayweather stays out of range and picks his opponents apart. This fight, Mayweather threw 3-4-5 punch combos which is rare in the latter half of his career.
But anyways, McGregor really does have poor technique. He doesn't turn his punches down and swings very wide which doesn't generate much power. He needs to sit down on his punches and generate power with his legs, hips and torso, but then again easier said than done when he doesn't really train for boxing.
Either way, he made a boatload of cash so he is probably very happy right now. Purse + PPV + endorsements + future earnings. He has instant name recognition from this fight and massive leverage against UFC. All month people were talking about this fight. He and his team will be expecting major paydays from now on because he is the biggest star in combat sports now. Business wise, McGregor wins.
