A lack of respect
Undefeated at 49-0. Biggest money spinner in the game. The most prized promotional icon of the sport. Easily the shrewdest business man cum sports athlete in the world. Greatest defensive boxer, perhaps of all time. Or simply, 'The Best Ever'.
When you think Floyd 'Money' Mayweather, you think about all of the accolades mentioned above.
When Conor McGregor thinks Floyd 'Money' Mayweather, he thinks about 'bouncing his little peanut head off the canvas'.
Many boxers before him entered the ring against Floyd in awe of his skills, at least secretly, and afforded him way too much respect in their fight. In some ways, they lost the fight before Floyd could ever beat them.
Conor McGregor, on the other hand, says that the only way Floyd can ever beat him is by 'reincarnating Bruce Lee'.
As disrespectful as McGregor's approach seems on the surface, that's exactly the kind of mentality that may help the Irishman on August 26th.
He needs to step into that boxing ring undaunted and express himself without cowing under the pressure of facing the undisputed king of boxing.
And so far, he seems par for course.
