“McGregor Stuns Mayweather!” Would Be Near the Top of This List Of Biggest Upsets In Sports History
If the oddsmakers in Las Vegas have it right - and they usually do (hey, those casinos weren't built on the backs of winning gamblers!) - Saturday's bout in Sin City between undefeated Floyd Mayweather and MMA superstar Connor McGregor is a very one-sided match-up favoring Mayweather. With a 49-0 lifetime professional boxing record, Mayweather is installed at -550 whereas McGregor's odds are being listed at +400.
If that doesn't make sense to you, we'll break it down a bit more simply:
If you were to lay down $100 on the Irishman and he pulled off the upset, you would win $400! If Mayweather, as the "sharps" are predicting, prevails your $100 wager would net you a whopping $18.18 profit.
If you are not the gambling type but still are rooting for the underdog nonetheless, Connor McGregor could put his name on this list of the biggest upsets in sports history compiled by ESPN.com:
