Boxing, like any other modern-day sport, is about money. It’s gambling and endorsements and financiers who want to make sure that they recoup their investment on the athlete(s) and make a profit on top of that.
And, today, sport is not about excellence per se. Excellence is qualified by which athlete catches the eye of a financier and, thus, be able to afford expensive trainers and have access to training facilities and equipment.
Again. Boxing, like any other modern-day sport, is about money.
