It makes him more human but it actually made him a lot more interesting and eased the pressure. Having struggles and failures makes anyone more relatable, less hateable, and all around more entertaining. His rivalry with Nate is one of the top highlights of his career so far.
People hate Mayweather cause he always wins, puts on boring performances, and rarely seems challenged.
Ronda was getting boring around the Bethe fight because she was just demolishing her competition in seconds, it wasn't even worth buying her fights, then she got absolutely outclassed and everyone immediately turned on her.
You don't wanna be flawless, it only makes the hate stronger and the downfall harder.
