Good thoughts, but I can't agree that there's a strong correlation between styles or in ring performance and character outside of it, fighting for a living is such a different thing in the first place. Mayweather is crude and stupid, probably very insecure and cowardly in many ways, that's not exactly what jumped out at you in the ring though is it. Likewise I'm sure there are lots of hard nosed, workmanlike fighters who always showed great sportsmanship and humility, but also went home and beat their wife and whatever else. At the end of the day, making a living by beating people up isn't something most people gravitate towards, there is far more of a common denominator there than there is in many things. To even include drug abuse as a factor when assessing a said persons character is kind of funny to me, as if that isn't in all walks of life.
