Dude you are showing a picture where a guy has his hands inside fucking boxing gloves , those were the circus days no doubt If MMA takes over boxing then it will get the top talent and will be better sport and the better fighters , as it stands now boxing have the better fighters and thats because they pay more and attract the top talent , saying who wins in a magical street fight is as dumb as it gets , why would a multi millionaire would be fighting in the streets ?
I will say it again , please try and follow for once , its ALL ABOUT THE TALENT , the sport that has the talent is superior in his level , if you enjoy it or not its a different question.
There is no doubt that NFL/NBA/Baseball/Soccer get the best talent athletes because thats where the money is and thats whats popular.
The fact that some of the NFL players are running 100M olympics finals results should tell you the level of athletes that sport attracts and the fact that they could've been in the US national team if they wanted too.
tldr- boxing has the better fighters currently , that might change in the future , talking about mythical street fights is childish.
FYI i would rather have 2 years in boxing as a casual in a street fight then a 2 years MMA training in a street fight , you want to be on your feet and avoid the ground as much as possible as you can get hit by others easily or get stabbed, bitten.
Saying that , Boxer will lose in MMA competition vs a competent MMA fighter , but thats irrelevant as they will lose in Judo vs a Judoka as well.
