Fans, fellow fighters, and opponents are well-acquainted with Conor McGregor’s hammer of a left hand. On the flip side, one of the long-running topics of conversation about “The Notorious” in terms of his weaknesses is his gas tank during fights.
Joe Rogan and Firas Zahabi talked about it a couple of years back. As Zahabi theorized, it’s possibly linked to genetics.
“McGregor, look at his stats. It’s all ‘round one knockout, round one knockout, round two knockout.’ He’s fast-twitch, high-leverage left hand. If you take him into deep waters, his fast-twitch muscle fibers cannot metabolize,” Zahabi explained, citing how Floyd Mayweather “let McGregor work for three rounds” to tire him out.
