Octagon jitters—it’s an infamous term. The first time a fighter steps into the UFC’s eight-sided cage, there will always be talk of whether the emotional rush and the nerves surrounding his debut will have a profound impact on his performance.

Pundits and fans making predictions on fights will cite the jitters as a reason to doubt a fighter’s chances. And in the aftermath of a defeat, these same jitters will take part of the blame for the fighter’s downfall.

So, following each UFC event, The MMA Corner will look at the fighters who made their Octagon debuts and provide impressions on their performances and their future potential under the UFC banner. In this edition, we focus on the 10 newcomers from The Ultimate Fighter: Brazil 3 Finale.

Matt Hobar — first-round TKO loss to Pedro Munhoz

Matt Hobar entered the Octagon as an 8-1 prospect. He left less than three minutes later after suffering a TKO loss at the hands of Pedro Munhoz.

Hobar, who has scored half of his victories by way of submission, was left with little choice but to stand with Munhoz, who is also an accomplished grappler. Hobar’s style, however, left him open to getting rocked by his Brazilian counterpart. Hobar tended to leave his chin unguarded as he leaned forward before throwing strikes. Munhoz was able to land a kick that rocked Hobar, then took the Legacy FC veteran to the mat. Hobar was too rattled to put up much resistance to the takedown attempt or the ground-and-pound that followed.

Hobar’s performance in the cage probably signals a one-and-done UFC stint. He found a lot of success under the Legacy banner, though, and perhaps with a few more wins, he’ll earn a second opportunity inside the Octagon.

Potential: Low

Marcos Rogerio de Lima — first-round knockout victory over Richardson Moreira

Marcos Rogerio “Pezao” may not be a natural heavyweight, but he certainly looked like a beast in the weight class during his first-round demolition of Richardson Moreira. Rogerio needed all of 20 seconds to score the knockout victory.

Pezao flashed a lot of power from the clinch, where he attempted to land knees before connecting with a big right hand. Knockout ability has been a theme throughout the 28-year-old’s five-plus years in the sport, but it wasn’t on display during the reality series, where he scored submission and decision victories before he was submitted by Antonio Carlos Jr.

Rogerio has one of the more noteworthy resumes of this TUF class. As a 7-0 fighter in 2010, he defeated former top middleweight Paulo Filho via unanimous decision. He then made an unsuccessful stop in Strikeforce, where he dropped a decision to Mike Kyle, a fighter who fluctuates between combat at light heavyweight and heavyweight. His only other loss came via knockout to Carlos Eduardo, a fighter who went on to compete in the Bellator cage.

Rogerio’s steamrolling of Moreira sets the bar high for his UFC career, but he probably won’t be able to demolish every fighter in the same manner. A move down in weight is a strong possibility, and it could allow him to find more consistent success with his power than he saw over the course of the reality series. A fighter who goes the distance with Kyle and scores such a violent knockout victory is also a fighter who should find a long-term home in the Octagon. He might never reach contender status, but Rogerio will settle in nicely as a gatekeeper.

Potential: Medium

Richardson Moreira — first-round knockout loss to Marcos Rogerio de Lima

There’s not much to be said about a performance like the one Richardson Moreira had on Saturday evening. It lasted 20 seconds and ended with Moreira out on the canvas. Moreira’s knockout loss to Marcos Rogerio de Lima put one more question mark—and a huge glove imprint—on the chin of a man who was knocked from the TUF Brazil 3 heavyweight bracket courtesy of a Vitor Miranda TKO finish.

Moreira tends to hunt for submission finishes, but he didn’t have a chance to do so against Rogerio. Immediately after the two men clinched, Rogerio let loose with knees and right hands to end Moreira’s night. Moreira’s punches to Rogerio’s body and head were well placed, but they were ineffective against Pezao.

The 30-year-old’s future potential cannot be assessed based off a mere 20 seconds of work. Moreira has had a lot of success in scoring first-round submissions, and he, too, was fighting above his natural weight class. Fighters will seek to test his chin, and if it doesn’t hold up, then his UFC tenure will be short-lived (assuming he even remains on the roster following his brutal loss). If he can protect his chin and work his submission game, however, Moreira could establish himself on the UFC’s roster.

Potential: Low to Medium

Ricardo Abreu — second-round submission victory over Wagner Silva

Ricardo Abreu may have missed out on a spot in the TUF Brazil 3 middleweight finals by one judge’s scorecard in a split decision loss to Marcio Alexandre Jr., but he recovered with a second-round rear-naked choke finish of Wagner Silva at the finale event.

Abreu sports a lot of power, but his approach isn’t always pretty. Against Silva, he had a tendency to chase his opponent. His striking wasn’t very technical, and he often relied on single punches or kicks while seeking to land one home-run shot. This approach led to his victory over Silva, but better opponents will time him as he moves forward. His instinct to chase could result in some knockout losses for the 30-year-old.

Abreu’s move to the submission was excellent, and his short five-fight career is evidence that he features a well-rounded ability to finish opponents wherever fights may go. Abreu’s style will earn him some victories inside the Octagon, but it will also account for setbacks that prevent him from ever reaching the upper tiers of his division.

Potential: Low to Medium

Wagner Silva — second-round submission loss to Ricardo Abreu

Wagner Silva entered the TUF Brazil 3 finale event as the least experienced competitor in the lineup. He had only three official fights to his name, but they were all victories. When he exited the eight-sided cage, it was as the recipient of his first official loss—a second-round rear-naked choke submission defeat courtesy of Ricardo Abreu.

Silva attempted to engage Abreu on the feet, but he kept his left hand low and didn’t use punches to set up his kicks. These two faults left him open to Abreu’s strikes. Silva also didn’t take advantage of Abreu’s tendency to chase him. However, despite those shortcomings, Silva’s biggest misstep was in pouncing on Abreu when he thought the fighter was rocked. Abreu capitalized to stagger Silva, setting up the beginning of the end.

Silva was the more technical striker, but he failed to use that quality to his advantage. His lack of experience, combined with the loss, is enough to send him packing. He needs more seasoning on the regional circuit, and after gaining more experience, there’s a chance he could return to the Octagon to find success. In this case, only time will tell.

Potential: Low

Alexander Yakovlev — unanimous decision loss to Demian Maia

Yes, Alexander Yakovlev survived numerous times while in Demian Maia’s mount, but does it really mean all that much? The Russian fighter ended up down on the scorecards in a lopsided decision loss to the Brazilian.

Initially, Yakovlev demonstrated good footwork and movement to avoid Maia’s takedown attempts. Really, though, it was only a matter of time before the UFC veteran took the newcomer to the mat. Once Maia started finding success on the ground, Yakovlev was left attempting to escape Maia’s mount. He wasn’t very effective in this regard. However, one noteworthy item is that Maia did not even attempt a submission from mount until the closing seconds of the fight. Maia’s focus in this fight was on patience, but, just like when he decided he wanted to box, this focus turned into a tunnel-vision effect. Maia captured the mount and was so patient that he never even tried earnestly to finish his opponent. Yakovlev might receive praise for surviving those bad positions, but it’s credit he doesn’t quite deserve.

The 29-year-old is already a very experienced veteran. His losses have come primarily against quality opposition, and he even earned a unanimous verdict over UFC vet Paul Daley. The Russian has a balanced game, but Maia exposed Yakovlev as a fighter with little to offer from his back. Granted, Maia is an ace grappler, but Yakovlev is going to have to improve his takedown defense and bottom game if he wants to stick around in the UFC. Given how completely Maia controlled him, he’ll be lucky to see a sophomore outing inside the Octagon.

Potential: Low

Warlley Alves — third-round submission victory over Marcio Alexandre Jr.

With a guillotine choke finish of Marcio Alexandre Jr. in the third round of their TUF final bout, Warlley Alves captured top honors in the TUF Brazil 3 middleweight competition. After eking his way into the house with a split decision, the aggressive fighter has displayed the knockout power and submission savvy necessary to compete at the highest levels.

Alves can be an extremely aggressive fighter—three of his official wins came in under two minutes and he had two first-round finishes in the TUF house. Alves’ bull-rush style can fluster opponents, as it seemed to do to Alexandre at certain points in their battle. He has strong takedowns and works well from the clinch, but he also possesses a dangerous guillotine that he’s not afraid to use.

At 23 years of age, Alves is another young, promising prospect that brings a well-rounded game to the Octagon. Like many TUF competitors, he was fighting up a weight class. He could return to welterweight, where his strength, power and submission skills will make him a tough opponent for anyone. With the TUF crown in his possession, Alves is certain to receive plenty of time to grow into a Brazilian star for the UFC.

Potential: Medium

Marcio Alexandre Jr. — third-round submission loss to Warlley Alves

Marcio Alexandre Jr. might utilize a similar stance to fellow karate practitioner Lyoto Machida, but, in his losing effort against Warlley Alves, he definitely wasn’t able to showcase the same elusiveness as the former UFC light heavyweight kingpin. Alexandre was tagged on the feet, taken down and submitted by his fellow TUF finalist.

Alexandre couldn’t avoid Alves’ takedowns, but he was good at escaping to his feet after landing on the mat. The big red flag, however, is that Alexandre was taken down on numerous occasions. The Team Tavares fighter, also fighting a class up from his normal welterweight home, didn’t flash much of the power that has accounted for 10 career wins by some form of knockout. The lack of finishing power as a middleweight was apparent on the show as well, where he struggled through the bracket with two split decisions on his way to the finals.

For a fighter known for quick knockouts, Alexandre’s run through the show and his loss in the finals are troubling. There is a chance that he’s simply giving up his power edge by moving up a weight class, and perhaps a shift back to welterweight will benefit him in future encounters. The UFC does have a tendency to give its TUF finalists a chance or two, so Alexandre might get his opportunity at 170 pounds. If the power returns, his potential could be upgraded. However, as it stands now, Alexandre’s potential in the UFC appears rather limited.

Potential: Low

Antonio Carlos Jr. — unanimous decision victory over Vitor Miranda

With a unanimous decision victory over Vitor Miranda, Antonio Carlos Jr. became the TUF Brazil 3 heavyweight victor. There’s just one problem: he’s not really a heavyweight, nor did he beat one. In what has become a tradition of The Ultimate Fighter competition, this was a case of two fighters competing above their natural weight classes in the hopes of securing a contract with the UFC. It doesn’t mean “Cara de Sapato” won’t succeed inside the Octagon, but it does mean that he’ll be seeking that success at light heavyweight (or even middleweight), and not heavyweight.

The 24-year-old has three submission victories on his official record, but he added one more submission and two TKO wins as he worked his way to the finals. Against Miranda, the Champion Team product continued to demonstrate his all-around game. Despite facing a kickboxer, Carlos was able to get the better of many stand-up exchanges. He looked strong in his takedown attempts and was able to transition to mount at one point against Miranda.

Whether he can continue to display that success rate on the ground is uncertain, but he only has four pro fights under his belt and the UFC will likely give him a few fights against lower-tier fighters to give him a chance to develop. Over the course of the reality series, he proved capable of withstanding and submitting a powerful striker like Marcos Rogerio, and he also proved that he can finish fights with his fists. As a TUF winner, he’s likely to have a slightly longer leash, but his skills already speak to his ability to establish himself as a fixture on the UFC roster.

Potential: Medium

Vitor Miranda — unanimous decision loss to Antonio Carlos Jr.

Vitor Miranda may have made it to the final bell with Antonio Carlos Jr., but he couldn’t top his foe on the scorecards. Miranda dropped the unanimous verdict and fell just short of earning the prize as an Ultimate Fighter winner.

A lot went wrong for Miranda in this affair. Despite his kickboxing chops, he wasn’t able to gain a striking edge against “Cara de Sapato.” That’s extremely disappointing after the knockout and TKO victories he posted on his path to the finals. Further stifling his chances at victory were the takedowns Carlos was able to implement to put Miranda on his back. Once on the mat, Miranda was able to defend impressively against Carlos’ submission attempts, but he did very little else en route to being controlled on the ground. He was even mounted by Carlos.

Like his TUF Brazil 3 heavyweight finals counterpart, Miranda isn’t actually a heavyweight. He’s more well suited for the light heavyweight or possibly even the middleweight division. Unlike the still-undefeated Carlos, Miranda has a number of losses that suggest he may be better at feeding on regional Brazilian talent than at stepping up to the big stage. There’s a small chance he sticks around for a fight in a more suitable weight class, but don’t expect him to fare much better there either.

Potential: Low
