How Raul Rosas Jr. Beats Raoni Barcelos: Chain the Takedowns

Everybody already knows the shape of Saturday's main event. Raul Rosas Jr. takes people down, Raoni Barcelos does not get taken down, and the headliner of UFC Fight Night 289 is filed under "strength against strength." Unstoppable force, immovable object, five rounds, pass the popcorn.

I think that framing is wrong in a useful way. It treats the takedown as a single event that either works or doesn't, and it treats Barcelos's defense as a wall that either holds or breaks. Neither man fights like that. The real question on Saturday is not whether Rosas Jr. can land a takedown on Barcelos. It is what happens in the four seconds after his first one fails. So let's look at the chain.

The chain, not the shot

The number everyone quotes from the Rob Font fight in March is 16 takedowns from 18 attempts. I care more about a number nobody quotes: Rosas Jr. held 10:05 of control across those 16 takedowns, which is about 38 seconds per takedown. Font kept getting up. That fight was not one long top-position ride. It was sixteen separate arguments, and Rosas Jr. won every one of them by starting the next shot before Font had finished standing.

Watch how that builds by round. In the first he landed 5 of 6 for 2:11 of control. In the second, 3 of 3 for 4:07. In the third he went 8 of 9, eight takedowns in five minutes, and Font landed three significant strikes in the round. That is the chain-wrestler's signature: the takedown count climbs as the other man's legs go, because every stand-up costs the defender energy and costs the attacker almost nothing if he is already in on the hips.

Compare that with how he beat Vince Morales a year earlier: four takedowns, 9:38 of control, roughly two and a half minutes per takedown. Against Aoriqileng it was three takedowns and 7:32 of control. Against lesser defenders he lands and stays. Against Font, a better defender and a much older one, he lands and lands and lands. Against a man who stops takedowns, Rosas Jr.'s path is volume and re-attack, not the perfect first entry. That is the only version of him that wins this fight on the mat, and it is the version that showed up most recently.

What happens when the chain breaks

There is one fight on Rosas Jr.'s UFC record where the chain broke, and it is the loss. Against Christian Rodriguez at UFC 287 he went 3 of 8 in the first round and banked 4:02 of control. Fine. Then he went 0 of 5 in the second and 0 of 3 in the third, 3 of 16 on the night, and the control swung the other way: Rodriguez held him for 3:37 in the second and 3:19 in the third, and landed 31 ground strikes in the fight, 23 of his 29 significant strikes coming in the last round.

Here is the part that matters for Saturday. Rodriguez landed exactly one takedown all night and still banked 7:30 of control. You do not get seven and a half minutes on top from one takedown unless the other guy keeps ending up underneath you on his own. The likeliest reading is the obvious one: failed shots turned into scrambles, and Rosas Jr. lost the scrambles. A missed double leg is not a neutral outcome. It is a man with his head low and his hips behind him.

The milder version is the second round against Aoriqileng in 2024: 0 of 3 on takedowns, no control, and a flat 17 to 17 exchange of significant strikes. When the shots don't land, Rosas Jr. becomes an ordinary bantamweight on the feet. His career output of 1.34 significant strikes per minute tells you he has never needed to be anything else.

Barcelos's wall

Now the other side. Across fifteen UFC fights, opponents have tried to take Barcelos down 41 times and landed 5. Cody Garbrandt went 0 of 7. Ricky Simon went 0 of 6. Timur Valiev went 0 of 6. That is not a man who merely sprawls well. Barcelos was a five-time Brazilian national freestyle champion and wrestled on the Brazilian national team before he switched to MMA, and he is a jiu-jitsu black belt under his father. He does not have to win the scramble with athleticism. He knows where it is going.

There is one crack in the recent record, and it is worth circling. In February 2024 Cristian Quinonez took him down twice in the first round, from six attempts, and held him for 3:13. That is the only round in Barcelos's last five fights in which anybody controlled him for longer than a minute and a half. Quinonez did it the way Rosas Jr. would have to do it: he kept shooting after the first one failed.

Then look at what happened next. Barcelos went 0 of 6 on his own takedowns in the second round, never stopped working, and submitted Quinonez at 2:04 of the third. The crack closed and the man on the other side of it got finished. That is the warning for Rosas Jr.: surviving a bad round on the bottom is something Barcelos has already done, recently, at 36.

Where Barcelos breaks it

Three places, in order of how much I believe them.

He shoots first. Rosas Jr. has almost no data on defending takedowns, because nobody tries. Across his eight tracked pro fights including the Contender Series, opponents have attempted four takedowns on him, and three landed. Our model's grappling inputs list his takedown defense at 25 percent against Barcelos's 88. Four attempts is a tiny sample and I would not build a house on it. But Barcelos is not a man who waits for a sample. He went 6 of 18 on Montel Jackson in April, spreading it 2, 1 and 3 across the rounds, and 8 of 15 on Payton Talbott in January 2025 for 9:43 of control. If Barcelos is the one hitting the first entry, Rosas Jr. is defending instead of chaining, and a chain wrestler who is defending is just a wrestler.

He wins the scramble that follows a failed Rosas shot. This is the Rodriguez fight with a much better grappler in Rodriguez's spot. Barcelos is the more decorated wrestler, the more decorated jiu-jitsu player, and a man with 0.7 submission attempts per fifteen minutes in the UFC. A 21-year-old who dives on his fifth shot of the round against a 39-year-old with a lifetime on the mat is making a trade, and Rodriguez already showed what the other side of that trade looks like.

He makes it a striking fight at distance. This is the weakest of the three, and I want to be honest about why. Barcelos lands far more than Rosas Jr. on the feet, but he has also been dropped in the first round in three of his last eight fights: by Umar Nurmagomedov, who stopped him at 4:40, by Kyler Phillips, and by Jackson in April. Rosas Jr. has one UFC knockdown, the one that finished Terrence Mitchell in 54 seconds. A standing fight is Barcelos's ground, but it is not free ground, and he has tended to pay for early exchanges before settling.

Rounds four and five

Neither man has fought past fifteen minutes in the UFC, so everything here is extrapolation. What I can say is that neither fades in the third. Rosas Jr.'s third rounds hold some of his best work: the 8 of 9 against Font, 4:19 of control against Aoriqileng. Barcelos's third rounds have been among his busiest: 34 significant strikes from 83 attempts against Simon, 37 from 52 against Talbott, three takedowns and 2:42 of control against Jackson.

Our model gives Rosas Jr. 70.6 percent, and when you open up what drives that number, almost all of it is age. The model reads him as squarely in his prime window and reads Barcelos as more than six years past it. After that the inputs are small: the switch stance, the layoff (203 days for Rosas Jr., 154 for Barcelos), their records before the UFC. The grappling block, the one built from takedown rate, takedown defense and control time, is the only input that leans Barcelos's way, and it is one of the smallest. I spent a whole piece on what the age gap does and does not tell you, so I will not relitigate it here. The market is less sure than the model. The consensus had Rosas Jr. at -184 on Tuesday and has drifted to -160, which is a price of roughly 61.5 percent.

So here is the breakdown as I would give it to someone watching with me. If Rosas Jr. lands early, lets go, and re-shoots before Barcelos is set, the way he did to Font, the chain wins and the rounds pile up in his favor. If Barcelos gets his own entries in first, or turns one failed Rosas shot into the kind of scramble Rodriguez turned it into, then the chain snaps and the fight belongs to the older man. Watch the first failed takedown in round one. Watch where Rosas Jr.'s head is when he comes out of it.

None of it may matter, or all of it may. Full card and our model's number for every bout are on the event page, and you can lock in your own call at the pick'em.
