28. Colby Covington and Jorge Masvidal
Covington and Masvidal are the two of the best UFC welterweight fighters on the planet. Both of them have brash personalities. The former is infamous because there is nobody he won’t insult. Meanwhile, Masvidal had an insane 2019 as he won the BMF title and built up a cult of personality around them. This teammate rivalry began at American Top Team in Florida.

Masvidal claimed that Covington failed to pay one of his coaches. This instigated a massive feud and escalated when ‘Gamebred’ called Covington ‘fake.’ To be fair, he was absolutely correct because the latter created a MAGA-loving persona that wasn’t totally real. The most likely outcome of this rivalry is that the pair will fight. They are no longer teammates because Covington moved to MMA Masters in Miami.
