Although the 2020 version of Conor McGregor has shown a different side of the former two-division UFC champion, make no mistake: “The Notorious” is still as cocky as ever.

McGregor (22-4 MMA, 10-2 UFC), who hasn’t competed since a quick TKO of Donald Cerrone at UFC 246 in January, is living in quarantine life just like most of the world. He’s been a major proponent of coronavirus awareness in his native Ireland and globally, and the time at home has given him some time to think, as well.

McGregor wondered out lout on social media Wednesday where his devastating left hand, which has produced so many career knockouts, ranks among the most dangerous weapons in MMA history. He ranked it at the top, putting himself above the grappling of his rival and current UFC lightweight champ Khabib Nurmagomedov, as well as other notable figures (via Twitter).

Conors left hand. Anderson’s front kick. Rondas armbar. Hendo’s bomb. Crocops high kick. Jon’s side kick to the knees over and over again and actually the only thing at this stage?Khabibs little mermaid leg wrap thing he does. What a sport! Who’s the greatest, you already know.

McGregor later deleted his tweet.

Naturally, McGregor’s comment was met with some venomous responses. Nurmagomedov (28-0 MMA, 12-0 UFC), of course, used his “little mermaid leg wrap thing” en route to beating McGregor by fourth-round submission at UFC 229 in October 2018.

There’s no denying McGregor’s left hand is a powerful tool, though. It helped lead him to flawless title-fight wins over Jose Aldo and Eddie Alvarez to claim featherweight and lightweight gold.

If McGregor is to ever wear a UFC title again, it’s a near-certainty his signature strike will play a large role in making it happen.
