Conor McGregor walks back into a cage on July 11 for the first time since he broke his leg against Dustin Poirier. Five years, almost to the day. He is a heavy underdog against Max Holloway in the UFC 329 main event at T-Mobile Arena in Las Vegas, and the fight-week noise has done what McGregor build-ups always do, which is get loud well before anyone throws a punch.

The case for him is not coming from where you'd expect. Michael Bisping, who has feuded with McGregor for years, spent this week arguing the public has him wrong.

the welterweight bet

The thread running through almost every pundit take is the same: the fight is at 170 pounds, a division Holloway has never fought in.

"I don't see how people can doubt Conor McGregor," Bisping told MMA Junkie. He admits he leans toward Holloway on his actual pick, but he kept circling the weight and the timing. "It's not going to be easy: five years away, 170 (pounds), that favors him early because we all know he's got the power," Bisping said. Combat sports has an old line about power being the last thing to leave a fighter, and Bisping leaned on it. If McGregor still has his accuracy, an early, clean connection is the live path to an upset.

Paddy Pimblett, who co-headlines the card against Benoit Saint Denis, went further. "Personally I think because it's at welterweight, I can see Conor knocking him out," Pimblett told UFC on TNT Sports. His logic was a comparison: Charles Oliveira made Holloway "look small" at lightweight, so picture the size gap a weight class up. Pimblett also flagged the flip side honestly. If it reaches the later rounds, he said, Holloway's cardio and volume "probably will start piecing him up on the feet." That is roughly the shape of the fight. Early, McGregor's size and power. Late, Holloway's engine.

Worth keeping the records straight on who Holloway is now. Per MMA Junkie he enters 27-9, and since McGregor last competed he has fought eight times, five of them title fights. The man McGregor beat in 2013 and the man across the cage in 2026 are not the same fighter.

the 2013 fight, and what it does and doesn't prove

McGregor has leaned hard on history. The two met at UFC Fight Night 26 in Boston in August 2013, and McGregor won. We can verify the result against our gold dataset: McGregor by unanimous decision on Aug. 17, 2013. What the box score also shows, and what McGregor leaves out, is that it went the full three rounds, with McGregor logging the bulk of his control time on the mat, about six and a half minutes of it. It was a grind, not the highlight-reel knockout he sells it as now.

The two finally stood across from each other this week, and McGregor picked up exactly where he left off in 2013. "People claim this man to be the No. 1 pound-for-pound featherweight of all time when I son'd him at that weight," McGregor said at the face-off, per MMA Fighting. He promised to "box you up with my hands down" and walk out "unscathed."

Holloway, to his credit, didn't blink, and he borrowed McGregor's own bit to do it. "Welcome to the Mystic Max era," Holloway said. "A bunch of gloves is going to get laid on that pretty face." McGregor's reply became the headline: "Max, you're not going to lay a glove on me and even if you do lay a glove on me, I'm going to laugh in your face." Holloway floated an immediate rematch at year's end if he wins. That's a lot of future being booked over a fight no one has seen yet.

the date Dana White won't confirm

Which brings up the one claim worth labeling clearly. McGregor has said his next UFC date is already set, telling media he'd be back in April for what would be the final fight of his current deal. Treat that as unconfirmed. Dana White did, publicly.

"What are the dates? I don't even know," White said at the UFC Vegas 119 post-fight news conference, per Bloody Elbow. "Let's get through this one first and then we'll figure out when the next one is." White's read was blunt: don't book fight two before fight one happens. He's right to. McGregor was scheduled to return against Michael Chandler in 2024 and pulled out injured. A pencilled-in April date is a plan, not a fact.

The card itself shifted this week too. Gable Steveson's debut against Elisha Ellison, originally slated to open the main card, dropped to the prelims, with King Green vs. Terrance McKinney promoted into the slot, per Bloody Elbow. The Olympic gold medalist still fights, just lower on the bill. The reshuffle changes the running order, not the lineup.

why we're not putting a number on this one

Here's where we'd normally give you our model's read. This time we're declining, and the reason is the honest one.

Our stack is built on fight history: recent form, opponent quality, the eye test backed by data. McGregor hasn't fought in five years and has never made the walk at welterweight in a sanctioned UFC bout at this stage of his career. The single most predictive input, "what has this fighter done lately," is a blank. Every number we could generate would be leaning on 2021-and-earlier data that may describe a man who no longer exists. We've owned our misses before, the Topuria HIGH-confidence pick that got knocked out, and the lesson there was to flag thin data rather than dress it up. This is thin data.

So no percentage from us on this one. The market has McGregor as a clear underdog, and that's a reasonable starting point given the layoff. But the gap between what a betting line can price and what anyone actually knows about a 37-year-old returning from a broken leg at a new weight is wide. Bisping said he's "very, very intrigued." Same. We'll watch this one like everyone else, and we'll grade ourselves after, not before.
