If you think at the top level of the sport, you're getting more damage done to you in a football game than a boxing match, you're delusional.
Esports doesn't require much physicality, the only thing you could argue is if you consider intellect or reaction time to be part of physicality. My argument is that the idea that being the goat requires the most physicality is a stupid idea, and doesn't make sense, especially if the goat in your eyes is Messi. The GOAT is the Greatest of All Time, not the GAOAT, the Greatest Athelete of All Time.
