Before we begin this list there are a few notable omissions that need clarifying. If a rivalry or feud is currently ongoing, as is the case with Conor vs. Nate, then it is not eligible to be on this list.
The reason for this is because we still don’t know where Conor vs. Nate will end up ranking on the all time rivalries list because there are still chapters that have yet to be written in the feud.
If Diaz wins again that will probably end the rivalry right there, but should Conor win or should there be a controversial finish at UFC 202 then we could see this show continue to play out over the next year and maybe even the next two years.
The same goes with Ronda Rousey vs. Miesha Tate or Holly Holm or even Amanda Nunes depending on what happens in the next women’s BW championship match. We may have seen the last Rousey vs. Tate matchup, but it’s likely we have not.
Of all the completed rivalries in the history of MMA these are the top seven.
