No Floyd is too old for even the current mediocre champions. he's better off sticking to Exhibitions and fighting YouTubers at his current age.
Floyd will punch him two or three times in every round to accrue points and spend the rest of the time on his bicycle. Romero is mentally challenged and is liable to fall for a simple plan.
The fact that a 3rd rate fighter like Romero even holds a belt is so ludicrous that boxing has lost any remaining credibility it may have had.
