What are some of the lessons of the fight? First is that the talk about McGregor fighting his first boxing match was overdone if for no other reasons that MMA fighters actually do box as part of their fights and McGregor has knocked people out with his punches. Mayweather admitted that McGregor was better than anticipated and McGregor southpaw stance was awkward for Mayweather to solve. McGregor also played counter puncher and his jab was effective enough over the early rounds to allow him to land some solid upper cuts. McGregor won the first three rounds and the fourth was close as well.
