Seeing how Floyd Mayweather has never lost a professional fight to any actual boxer, oddsmakers rate him as an overwhelming favorite if the much rumored boxing match against mixed martial arts star Conor McGregor comes to realization.
Mayweather is listed as a -1400 betting favorite against the +750 underdog McGregor at sportsbooks monitored by OddsShark.com. If it happens – and McGregor has been dropping hints that it will, sharing video of him training for boxing in Mayweather’s hometown of Las Vegas – it would also be the most lucrative bout in prize fighting history.
Mayweather, who turns 40 years old next week, is a perfect 49-0 during a career which has seen him win acclaim as the best fighter, pound for pound, of the last quarter-century. The five-division world champion has stayed on top of the game for so long by being an excellent defensive fighter who wears out opponents.
Mayweather’s last seven victories as well as 10 of his last 12 have gone the full 12 rounds. At this stage of his career, he’s far from a knockout artist but is likely to be able to keep his guard up much better than the typical opponent McGregor faces in the Octagon.
McGregor, the UFC lightweight champion, ends his fights quickly. The Irishman has won 17 of his last 18 bouts, including 14 by knockout or technical knockout. Stamina likely wouldn’t be an issue for McGregor in a boxing ring, given that boxing rounds are two minutes shorter than the five-minute rounds in the UFC.
Of course, if the fight actually comes to pass, McGregor would have to adjust to using the heavier boxing gloves and would have to get used to staying on his feet.
Since coming to the UFC, McGregor has been an underdog only once, closing at -105 against Jose Aldo at UFC 194. That was the bout where he knocked out Aldo in 13 seconds.
