McGregor’s Odds Against Mayweather Shift Slightly As Speculation Intensifies

Seeing how neither Conor McGregor nor Floyd Mayweather have any weight classes to conquer, the logical – and lucrative – next step for the two fighters is to have a boxing match.

McGregor would be coming over from the Octagon to the ring where Mayweather has a lifetime’s worth of specialized boxing training. Not surprisingly, the Bovada sportsbook shows McGregor is a +550 underdog against -900 favorite Mayweather in the event their much rumored mega-fight takes place. That’s an improvement for McGregor, who had been a +750 underdog earlier in the week.

Reports this week suggested that the UFC lightweight champion and the undefeated five-division champion have agreed to terms for the fight, leading many to speculate that the only barrier is making sure McGregor fulfills his contractual obligations to the UFC and president Dana White.

Since coming to the UFC in 2013, McGregor has been both featherweight and lightweight champion. The Irish fighter has also become a premier knockout artist, winning 17 of his last 18 fights with 14 of those victories by knockout or technical knockout.

Odds-wise, McGregor has only been the betting underdog once. He closed at -105 ahead of his featherweight unification bout against Jose Aldo at UFC 194 in December 2015. Of course, McGregor won that fight in 13 seconds.

McGregor boxed as a teenager, but fighting as an amateur hardly holds a candle to getting in the ring with Mayweather. Boxing rounds are three minutes long compared to five in the UFC, so having the conditioning and stamina might not be an issue. Of course, McGregor is light-years removed from Mayweather technically and, on top of that, would have to adapt to wearing heavier gloves.

Astoundingly, these are not the most overwhelming odds in favor of Mayweather during his career. He was listed at -3000 before defeating Andre Berto in September 2015. That bout 17 months ago was the last time that Mayweather, who is 49-0 as a pro, stepped into the ring. Some will wonder what that layoff will mean for a fighter who turns 40 before the end of February.

That said, if Mayweather takes the fight, it probably means that he is confident nothing will happen that would put a blemish on his career record. The five-division world champion is excellent technically, which is why 10 of his last 12 wins stretching back to 2006 have been by decision.
