The only thing better about other sports over boxing

The fact that any sports teams are forced to play other teams regardless, unlike boxing which has missed out on many of great fights because the fighters can choose who they fight. They are forced to play the teams within their conference multiple times and if they keep winning will eventually face the best teams in the other conference. So even if the best 2 teams in the sport are opposite conferences they will have to face each other in the finals. Mayweather and Pacquiao are the two best fighters in boxing, yet we already missed out on the fight once and very well might happen a second time. I think it is good that fighters can decide who to fight but to an extent. The idea of the alphabet belts making mandatory challengers is good on paper but they seem to always have shitty mandatory fighters. I wish boxing would mandate the top 2 fighters in the division or the best match up to fight each other so then we wouldn't have this kind of problem. Its a shame we have had too many great fights not happen and might not get to see the possibly greatest fight of our generation. Other than that I really don't like anything else about other sports besides boxing.
