UFC 300 takeaways: Pereira's triple-champ aspirations, Holloway holds all the keys

On a historic night in MMA, UFC 300 delivered throughout its loaded 13-fight card with big finishes, strong debuts and drama throughout the night.

Alex Pereira leaves Las Vegas with no doubt as to who is the UFC's best light heavyweight. Zhang Weili and Yan Xiaonan made China proud with their historic moment as well with a five-round thriller in the co-main event. Plus, the BMF title fight allowed fight fans to witness one of the greatest knockouts in the history of the sport. Also, what does Kayla Harrison's debut mean for not only her new division, but for women's MMA as a whole? Andreas Hale, Brett Okamoto, Marc Raimondi and Jeff Wagenheim react to the biggest moments of the night.

Wagenheim: Let's begin with a hard truth: Alex Pereira vs. Jamahal Hill was not the first choice to headline the milestone event that was UFC 300. But because the matchmakers could not put together a star-studded blockbuster to headline, that's what we ended up with. And guess what: The fans won.

They got a night full of championship-level fights, with 11 current or former UFC champions in action. (Titleholders past and present went 7-4.) The BMF gimmick had its greatest moment, with Max Holloway delivering one of the most legendary knockouts in MMA history. There was the much-anticipated debut of Kayla Harrison and a showcase for the sport's top prospect, Bo Nickal. It was a thrill a minute through almost all of the 13 bouts.

Would we have gotten all that if the UFC had assembled a Conor McGregor or Jon Jones main event for 300? Not a chance.

And a tremendous night of fighting ended with a tremendous first-round knockout, one that had both scary and comical elements to it. The funny part was when Pereira absorbed a shot to the groin (not funny to him, I'm sure), and as Herb Dean stepped in to pause the action, Pereira pushed the referee aside so he could deliver some punishment back. He then stepped forward and landed a short left hook that had Hill knocked out before he even hit the canvas, giving Pereira the first defense of the light heavyweight title he won in November. The end of the fight displayed the scary power of a man competing at a weight class 20 pounds heavier than the division he called home before last summer.

It was Pereira's eighth UFC fight, and he has been a champ in two divisions -- light heavy and middleweight. He came to MMA after being a world champion in kickboxing. And he might not be done seeking out bigger challenges. In his interview after the fight, Pereira spoke of wanting to take a heavyweight fight. Would his power follow him there? It sure has so far.

Holloway raises iconic status with dramatic BMF win

Raimondi: Max Holloway is simply one of the best fighters ever to put on a pair of gloves.

He's one of the greatest featherweight champions of all time. Now he's the BMF titleholder after perhaps the most iconic knockout in UFC history. Holloway won 13 in a row at one point at featherweight, the longest streak in division history. And now, 12 years into his UFC career, he's still putting on performances such as the one he had Saturday night, sleeping Justin Gaethje with one second left in the five-round fight. Legendary stuff. Iconic stuff. Hall of Fame stuff.

Afterward, Holloway called out Ilia Topuria and Islam Makhachev, two UFC champions. Topuria holds the featherweight title and Makhachev is the lightweight champ. The funny thing is, after mollywhopping Gaethje, Holloway legitimately has a case for either title shot.

It's kind of absurd to consider, especially since people were worried about Holloway in this fight. They were concerned that Gaethje, an absolute monster of a striker with big-time power, would be the first to stop Holloway in the Octagon. Of course, the opposite happened. This is the fight Holloway wanted, as he called for it in October on social media. He got it and cemented his legacy as an all-time great on one of the biggest cards of all time, UFC 300. That's storybook stuff. Movie stuff. Blessed stuff.

Zhang retains, but Yan exposes potential cracks for future challengers

Raimondi: Zhang Weili's win over Yan Xiaonan at UFC 300 was a matter of perspective. She basically choked Yan out at the end of the first round. When the bell sounded, the two fighters got up, and Yan was visibly wobbled, barely able to stay on her feet. That could have been the end, but referee Jason Herzog allowed the fight to continue.

In the second round, Zhang teed off on Yan from back mount, smashing her with big punches to both sides of the head. It was a dominant stretch. But then, Zhang seemed to have punched herself out. Or maybe her arms were toast from the long choke attempt. Yan knocked Zhang down a couple of times and lasted the full 25 minutes.

Zhang won by unanimous decision, and it was mostly a one-sided performance. But it wasn't the spectacular performance that Zhang likely wanted against her Chinese countrywoman. Interestingly, Zhang looked much more comfortable on the ground than on the feet, similar to her fight against Amanda Lemos.

As good as Zhang can look during stretches -- she's as skilled and explosive as any woman to ever fight in the UFC -- she has vulnerabilities that can be exploited. If Tatiana Suarez can stay healthy, a title fight between her and Zhang would be a must-see clash.

Harrison 1, Scale 0

Wagenheim: Kayla Harrison faced a formidable opponent at UFC 300. It was the scale she had to step onto at Friday's weigh-in, where she had to make the 136-pound bantamweight limit after competing for nearly her whole career 20 pounds north of that. As expected, Harrison looked gaunt and depleted -- but she made weight like the pro she is.

And when she stepped into the cage on Saturday, Harrison appeared to have rehydrated to an approximation of her old lightweight self. Then she dismantled Holly Holm, a former UFC champion who became a superstar almost a decade ago by crushing Harrison's old judo teammate and fellow Olympic medalist, Ronda Rousey. Holm, 42, did not stand a chance on this night. The 32-year-old version of "The Preacher's Daughter" might not have had a prayer against Harrison, either.

If Harrison gets used to the weight cut, there's no stopping her. She's too brawny for women's bantamweight champ Raquel Pennington, and the same goes for everyone else in the division's top tier. I wrote this the other day and still believe it: Harrison's toughest competition resides in the PFL with Cris Cyborg and Larissa Pacheco. But that ship has sailed, so there's no stopping Harrison from taking over the UFC's 135-pound division.

Hale: On a star-studded fight card, not all of the biggest moments involved a title belt. Here are a few other angles to follow as the lights go down in T-Mobile Arena.
