Mayweather doesn't take a fight unless he knows he's going to win, but McGregor definitely has a strong chance. I don't believe that sparring video of McGregor is legit though, they're both trying to sell a fight. They both know how to bring the crowd in and it's going to be a hell of a fight in my opinion. Not a mickey mouse fight like everyone thinks it's going to be. My money is on McGregor, mainly because he's 5/1 lol. No matter what happens it's going to be a good night for boxing and mma, whoever wins.
