The second round of our 32-fighter tournament picking the best champions in UFC history has wrapped up and the quarterfinals have arrived.

On Friday, we asked what would happen if we took the best champions in UFC history and matched them up, bracket style? Who would wind up the best champ of all time?

So with the NCAA Tournament’s Final Four upon us, we’re giving you the chance to vote for your favorite UFC champions ever.

Now that the quarterfinal round is here, things went almost to plan – at least based on fighter seeding. We have three No. 1 vs. No. 2 matchups. The fourth is a No. 1 vs. No. 3 – thanks to a bit of an upset. Current heavyweight champion Stipe Miocic, beat inaugural women’s bantamweight champ Ronda Rousey to advance to a meeting with Jon Jones.

Check out the bracket above (or open it in a new window here), then click through to vote in our polls for each of the new matchups. The voting in the quarterfinals will end Sunday at 9 a.m. ET, and we’ll get the semifinal round going after that. Everything will culminate Monday night when we crown our all-time best champ – through your votes – around the same time we have a new NCAA men’s basketball champion.

(Disclaimer: Fighter seeding was done largely based on total number of title defenses. To make the field, fighters had to have had at least two successful title defenses and/or have held the rare distinction of being a two-division champion. Two fighters qualified, but in part through interim title fight wins. In that case, Renan Barao and Andrei Arlovski met in a play-in game, and Barao got into the field based on one more win in a title fight than Arlovski.)

Sound off in the comments – but most importantly, just vote. And if you want to take a look back at the first two rounds of voting, you can see the percentages in all the poll matchups here:
