In the history of sports, the main focus has always been on big guys, big egos, and big performances.
It explains why, when it comes to combat sports, the physically biggest guys (heavyweights and light heavyweights) tend to be the headliners.
Unfortunately, due to factors ranging from age and injury to fatigue and out-of-sports issues, the UFC heavyweight and light heavyweight divisions are not as compelling to follow as other weight classes.
