  • Spivac averages 4.63 takedowns per fight with 65% accuracy vs Delija's limited UFC grappling data
  • Delija suffered TKO losses in 2 of last 5 fights, showing declining durability at 35 years old
  • Spivac's submission wins over Lewis and Tybura demonstrate elite heavyweight grappling
  • 1-inch height advantage to Delija negated by Spivac's superior wrestling and 260lb frame
Write-up

Spivac's grappling-heavy approach and submission expertise create significant problems for Delija. Despite recent losses to elite competition (Gane, Almeida), Spivac has shown consistent submission threat against mid-tier heavyweights. Delija's recent TKO losses to Cortes-Acosta and Moldavsky expose defensive vulnerabilities that Spivac can exploit through his 4.63 takedowns per fight average. The common opponent in Cortes-Acosta saw both fighters lose, but Spivac's decision loss shows better durability than Delija's TKO defeat.

  • Massive grappling volume and efficiency edge for Spivac (4.63 TDs/15 at 65% accuracy vs. Delija's unproven UFC-level defensive metrics)
  • Spivac's historical success against mid-tier heavyweights with similar size but weaker wrestling defense
  • Delija's best chances are early striking exchanges, but Spivac's path to victory via clinch, trips, and mat returns is more reliable over time
Write-up

Spivac is a proven UFC heavyweight with a strong wrestling and top-control game (4.6 TDs per 15 minutes at 65% accuracy) and consistent finishing ability on the mat. Delija is debuting in the UFC and historically has struggled when forced to defend prolonged grappling sequences. Over three rounds, Spivac's takedown volume and positional control should create repeated opportunities for ground-and-pound and back takes, making a club-and-sub or top-pressure submission the most likely outcome.
