6. Jose Aldo vs. Frankie Edgar – UFC 200
Yet another pointless interim belt created due to Conor McGregor.
This one was even more unnecessary than Ferguson vs Lee, as Aldo had literally just lost the featherweight belt to McGregor by knockout in only 13 seconds just months before his interim title bout with Edgar at 2016’s UFC 200.
The trend here, and it isn’t hard to see, is that McGregor opts to win belts and not defend them. The UFC had to do something to keep the 145-pound division moving, as McGregor had already made his intentions to fight for the lightweight belt immediately after capturing the featherweight title known.
Aldo beat Edgar as he did in their first fight back at UFC 156, but absolutely no one recognized the Brazilian as a champion of any sort following his lightning-fast KO at the hands of McGregor.
Aldo was crowned the actual champ after McGregor was stripped of the 145-pound title, but would go on to lose to Max Holloway by TKO at June 2017’s UFC 212.
