American sports pursue something called ‘parity’. It is rather unusual to the global sporting world, but in the North American sporting culture, it is rather normal.
This includes processes like reversing the draft order, introducing a salary cap, limiting the spending power of the richer organisations, and using roster designations which again restrict the number of great players can be hoarded by individual teams.
Major League Soccer, despite being a football league, a sport that predominantly does not believe — or at least exercises — parity, also tries to introduce this rather awkward, contorted and yet exciting and admirable characteristic.
