Almost every single fighting & strength based sport is separated into different weight classes with people only competing within their class. This allows people with all different sorts of body shapes to train and compete with other people who are roughly equal to them.
Something like basketball on the other hand, only a tiny, tiny fraction of the population is even born with the genetic makeup to ever hope of attempting to play professionally. Why not add height classes to basketball so that more people are able to play the game? Has anyone proposed this? Would it make the game of basketball more entertaining IYO?
