Stipe Miocic avenged his 2018 loss to Daniel Cormier and regained the UFC heavyweight championship. Paulo Costa and Yoel Romero had a middleweight exchange on the feet for the ages. Three years removed from his last fight, against Conor McGregor, Nate Diaz made an instant splash.

Our panel is here to break down the biggest moments of UFC 241.

Is Stipe Miocic the greatest heavyweight in the history of the UFC?

Ariel Helwani: These questions are always hard to answer on fight night. However, I lean toward yes for two reasons: He has the most title defenses in UFC history, and he just beat who I considered to be the best heavyweight ever. Also, in case you didn't know, Cormier was a perfect 15-0 as a heavyweight going into Saturday. In other words, that win was really big for Miocic. It was, in my opinion, his biggest to date.

Brett Okamoto: Yes, Stipe is the greatest heavyweight of all time, as of Saturday night. His goal was always to be the greatest of his era, and there would have been no coming back had he lost to Daniel Cormier. That goal would have been dead. But he delivered a performance for the ages against one of the greatest fighters of all time. Unless there is a trilogy -- a scenario that seems very unclear to me right now -- I would say Stipe is the greatest heavyweight.

Jeff Wagenheim: If you had asked me this question early in the evening of July 7, 2018, I would have said yes. Miocic had defended the belt more times than anyone else, most recently dominating Francis Ngannou, the scariest KO artist this side of prime Mike Tyson. Prior to that, he had KO'd a former champion (Andrei Arlovski), the reigning champ (Fabricio Werdum) and his first two challengers (ex-belt holders Alistair Overeem and Junior Dos Santos) -- all in the first round. But then, on that ill-fated night last summer, Miocic went out and got KO'd in the first round, and we had to slow our roll on GOAT talk.

On Saturday, though, he righted that wrong, and he did it in a way seldom seen from heavyweights. When the big guys are being beaten to the punch in the early going, it usually turns into an early night. But Stipe persevered through the best that Daniel Cormier could dish out, turned the tide in Round 3 and came out for the fourth with a whole new plan of attack, which he implemented with poise and precision. That's high-level stuff, the kind of fighting you see from only the greats.

Or, in this case, the greatest.

Marc Raimondi: I don't think there's any way around that now. Miocic came in already holding the UFC record for consecutive heavyweight title defenses at three. Now, he's a two-time champion with a TKO win over Daniel Cormier, one of the best fighters ever, on his résumé. If Miocic isn't the greatest heavyweight in UFC history, then who is? Cormier? Cain Velasquez? Miocic has the edge over both, especially now. At 36 years old, Miocic is still going strong too.

If this was it for Daniel Cormier, what is his legacy in the UFC?

Helwani: One of the greatest ever. Top five. A living legend. A fighting champion. A man who got knocked down repeatedly and found a way to overcome it all toward the end of his career. I have the utmost respect for Cormier. He never took a shortcut and represented the sport with dignity and class. He has nothing left to prove to anyone. The Hall of Fame awaits.

Okamoto: Cormier's legacy is as one of the greatest fighters of all time. There should always be a footnote attached to his career that he got in late. Had Cormier started training in MMA and transitioned into MMA earlier than he did, I think there is a very strong chance that we would call him the best of all time. And he still had a tremendous career. Fifty years from now, we'll still be talking about the greatness of Daniel Cormier. This loss has no effect on that.

Wagenheim: Cormier is one of the greatest figures in the sport. As a fighter, he has beaten everyone he has faced other than Jon Jones, and there's shame in that only if you can find shame in beating everyone in one-on-one hoops except Michael Jordan. Speaking of greats, among Cormier's conquests is the finest heavyweight ever to walk the earth (even though Miocic evened the score on Saturday).

Beyond fighting, DC's legacy is still building. He's the most fun among the cageside analysts ("Thug Rose! Thug Rose!"), and consider this: The three figures who break down athletes on the Detail show are Kobe Bryant, Peyton Manning and Cormier. DC is no interloper in that elite company.

Raimondi: He's one of the top three MMA fighters who has ever lived. As it stands now, I put Jon Jones and Georges St-Pierre above him, but that's all. Cormier is a former UFC heavyweight and light heavyweight champion. He has lost to only two men, Jones and Miocic. There is no doubting his résumé. Just as important is how great of an ambassador he is for the sport. Cormier is an exceptional analyst on ESPN and is a credit to MMA in every position the UFC puts him in outside the cage. The best part is the latter doesn't have to end even if he does hang up the gloves.
