In combat sports, the wheel turns because the young eat the old. Relatively unknowns make their names by battering older, established stars. It’s the job of the promotion to facilitate this natural process to some degree.
A relatively recent UFC pickup like Duncan — 32 years old with just eight total UFC fights — strings together a few nice finishes, so his reward is a ranked former title challenger who looked a bit shopworn in his most recent appearance. What comes next should be simple enough. The UFC’s 155-pound division, however, continues to defy this trend.
The aging group of Lightweight contenders and former champions have largely refused to be replaced and are winning more of these matchups than not. The Lightweight Top 15 of today contains many of the same names from five years ago, when fans were already discussing their inevitable replacement. There has been some movement, of course.
