Cortes-Acosta brings a methodical, patient approach to the heavyweight division that's been serving him well. In his recent unanimous decision victory over Robelis Despaigne, he showcased his fight IQ by recognizing Despaigne's limited offensive arsenal and executing a brilliant gameplan. Instead of recklessly pursuing a knockout, Cortes-Acosta waited for Despaigne to overcommit, then secured multiple takedowns in the first and second rounds, effectively neutralizing the 6'7" taekwondo specialist.
Against veteran Andrei Arlovski, Cortes-Acosta employed a clinch-heavy strategy, using his size and strength to control the 45-year-old along the cage. His persistent pressure and dirty boxing in close quarters earned him another decision win. When facing Lukasz Brzeski, Cortes-Acosta demonstrated his developing striking skills, using a stinging jab followed by powerful straight rights while maintaining pressure against the cage. This approach gradually broke down Brzeski's defense and cardio, leading to a first-round KO victory.
What's particularly impressive about Cortes-Acosta is his improved cardio management. Unlike many heavyweights who gas quickly, he's shown an ability to throttle back when necessary to preserve his energy while maintaining effective offense. His only UFC loss came against grappling specialist Marcos Rogerio de Lima, where he struggled to implement his preferred striking game.
Spann is a dangerous finisher with 16 first-round stoppages in his career. His guillotine choke is particularly lethal, accounting for 10 of his 13 submission victories. We saw this technique's effectiveness in his quick win over Ion Cutelaba, where Spann capitalized on Cutelaba's aggressive takedown attempt by securing a devastating guillotine that applied direct pressure to the windpipe rather than just squeezing the sides of the neck.
In his knockout win over Dominick Reyes, Spann's explosive power punching was on full display. His big right hand found the mark against Reyes, who was already compromised from previous knockout losses. Against OSP in October, Spann once again showcased his quick submission skills, securing another first-round finish.
However, Spann has shown vulnerability when his initial attacks don't lead to quick finishes. Against Bogdan Guskov in April, Spann started strong with a takedown and top control in the first round, but appeared to slow down as the fight progressed. Guskov capitalized with a perfectly timed right uppercut as Spann was jabbing, leading to a second-round KO. Similarly, in his loss to Nikita Krylov, Spann made a critical error by rushing headlong at Krylov who was on his back, essentially diving into a triangle choke position.
Size and Division Shift: This marks Spann's move to heavyweight after fighting at light heavyweight. While he has the frame (79" reach), the adjustment to facing bigger, harder-hitting opponents presents significant risks.
Striking Defense Differential: Cortes-Acosta's 52.9% significant striking defense percentage outpaces Spann's 44.5%, suggesting he's the more defensively responsible fighter. This could be crucial as exchanges develop.
Pacing and Cardio: Cortes-Acosta has proven his ability to maintain effectiveness over three rounds, as seen in his victories over Despaigne and Arlovski. Spann has shown a tendency to slow down when unable to secure an early finish.
Clinch Work: Against the fence, Cortes-Acosta excels at dirty boxing and control, as demonstrated in his fight with Arlovski. This could neutralize Spann's height and reach advantage.
First Round Danger: Spann's 16 first-round finishes make him extremely dangerous early. Cortes-Acosta must weather the initial storm while avoiding the guillotine choke that finished fighters like Cutelaba and OSP.
Several statistical factors influenced WolfTicketsAI's pick of Cortes-Acosta:
Conversely, some factors decreased confidence: - TrueSkill reduced the score by 4.0, suggesting Spann's overall skill rating might be higher - Recent Takedowns Attempted decreased the score by 2.0, possibly indicating Spann's grappling threat - Average Striking Output Differential and Recent Average Striking Output Differential each reduced the score by 1.0
WolfTicketsAI has a mixed record predicting both fighters. The model correctly predicted Cortes-Acosta's victories over Brzeski and Arlovski, as well as his win against Sherman, showing good accuracy when backing him as the favorite. However, it failed to predict his victory over Despaigne, incorrectly favoring the taekwondo specialist.
With Spann, the model has been less accurate. It correctly predicted his submission victory over OSP, but missed on his KO victory over Reyes and his submission win over Cutelaba, both times backing his opponents. The model also incorrectly predicted Spann would defeat Guskov and Anthony Smith.
This inconsistent prediction history, particularly with Spann, suggests some caution is warranted despite the model's confidence in Cortes-Acosta.
Cortes-Acosta's patient approach, superior striking defense, and proven cardio give him the edge over Spann's explosive but sometimes reckless style. While Spann presents serious first-round danger with his submission skills and power, Cortes-Acosta's ability to weather early storms and implement strategic pressure should allow him to take control as the fight progresses. WolfTicketsAI predicts Cortes-Acosta will neutralize Spann's early attacks and secure the victory through his more measured, defensively sound approach.
