Yes.
With VERY few exceptions, no rich kids from places like Scarsdale, NY, Stamford, CT, Beverly Hills, CA, or Highland Park, IL would end up forgoing their bachelor's degree at the Ivy Leagues for a career in fighting.
Even a guy like BJ, who has family money, isn't highly educated. His family made some money in real estate in Hilo, kind of like some mah-jong playing Chinese grandma who owns a building in San Francisco.
The whole "MMA fighter who is smart" is highly overrated. None of these guys had admission to MIT and a job at Google in their future.... and yes, I know there are a 100 high school math teachers in every county in the USA, there are tons of people that majored in communications at Boston College, etc. I'm not impressed.
I do think that Joe Lauzon is the lone brilliant mind in high level MMA. His education level is 'meh' but he is a very smart guy, albeit probably also from a lower middle class background. Not a pro level athlete by any means, but performed to a very high level due to his own intelligence, not due to the intelligence of his coach.
The story might be a clich
