Quick read

A detailed post-fight analysis suggests Khamzat Chimaev may have been preparing for a light heavyweight debut before plans changed last minute, which could explain his poor cardio showing at UFC 328. The analyst notes that despite Sean Strickland's pre-fight trash talk, Chimaev repeatedly extended his hand, smiled, and embraced his opponent, which only looked good because he didn't dominate in the cage as expected. Instead, Chimaev was on his back under Strickland by the second round. The theory from analyst Vlad Matveev proposes that Chimaev's preparation under top sports science professionals wouldn't normally result in cardio lasting only one round, suggesting the weight cut to 185 pounds may have been the issue. The post also includes analysis of other fights on the card, including comparisons of Pantoja-Taira to Moreno-Figueiredo.

Post-fight analysis published following UFC 328 is raising questions about Khamzat Chimaev's preparation heading into his middleweight bout against Sean Strickland on May 9, with analyst Vlad Matveev suggesting the No. 1-ranked contender may have been training for a light heavyweight move before pivoting back to 185 pounds at the last minute.

Chimaev, 32, entered the fight carrying a 15-1 record and a pound-for-pound ranking of No. 10 in the world. Known for elite grappling output — he averages 5.29 takedowns per 15 minutes with a striking accuracy of 60 percent — the UAE-based Swede was expected to impose his will on the champion. Instead, Matveev's analysis notes, Chimaev found himself on his back under Strickland by the second round, his trademark pressure and physicality conspicuous by their absence. The theory holds that a training camp geared toward a higher weight class, followed by a sharp cut back to middleweight, would explain a cardio collapse that Matveev argues would be otherwise uncharacteristic for an athlete working under elite sports science staff.

On the other side of the cage stood Strickland, the reigning middleweight champion at 35 years old. The American out of Xtreme Couture carries a 31-7 record and lands an aggressive 6.04 significant strikes per minute, using a six-foot-one frame and a 76-inch reach to maintain consistent output. Matveev notes that Chimaev's courteous behavior before the fight — extending his hand and embracing Strickland despite the pre-fight verbal exchanges — read differently in hindsight given what followed inside the octagon.

The analysis also draws broader card-level observations, comparing the Pantoja-Taira flyweight contest to the celebrated Moreno-Figueiredo rivalry. Tatsuro Taira, ranked fifth at flyweight at just 26 years old, holds an 18-2 record and averages 3.12 takedowns per 15 minutes with a submission attempt rate of 1.6, reinforcing his reputation as one of the division's most dangerous grapplers.

Why it matters

  • A late weight-class change in camp, if accurate, would reframe the Chimaev performance significantly
  • Strickland's middleweight title reign gains credibility after defeating the division's top-ranked contender
  • The Taira-Pantoja comparison signals the flyweight division's rising profile alongside the established rivalries that defined it
