In honor of the “weekend of upsets” in the Men’s NCAA Basketball tournament, MMAFrenzy is taking a look back at some of the biggest upsets in MMA history. What started as a simple top ten list morphed into a full-blown 32-fight bracket. While no list is perfect, these were the top 32 upsets the staff agreed on. Voting on the first round will last two days, with the second round beginning Friday.
We judged the upsets on the basis of fight odds, skills, fighter ranks, and the surprise factor. We tried to minimize a hindsight bias by focusing on where these fighters were at in their careers at the time of the upsets rather than where they are now.
Again, voting on the first round will last two days, with the second round beginning Friday.
