This is the most interesting pricing tension on the card. The market makes Jones a strong -340 favorite (74%), but the opponent-adjusted Elo model actually favors Mederos 57-43, a genuine model-vs-market split worth resolving. Jones brings the pedigree: 18-2 overall, a three-fight UFC streak including an elbow TKO of Bolaji Oki, and a dual-threat game (5.61 SLpM plus 3.16 TD/fight at 45% accuracy). But his 46% striking defense is genuinely leaky, he absorbs 4.94 SApM and wins through attrition and pace rather than cleanliness. Mederos is the stylistic antidote on paper: unbeaten in the UFC (3-0-1), 63% striking defense, and a 90% takedown defense rate that should blunt Jones' wrestling entries and force a pure kickboxing fight where Jones eats counters. The problem for Mederos is offense, he's a 45%-accuracy, 4.39 SLpM decision grinder with zero UFC finishes who just fought to a majority draw against Chris Padilla, and he cedes 5 inches of reach. Jones' relentless forward pressure and volume edge should win the optics of close rounds, and his opposition quality (Onama, Klein, Stephens) exceeds Mederos' slate of Choinski/Hubbard/Quinones. I side with Jones by decision but at a materially lower probability than the market's 74%, closer to 60%. Mederos' takedown defense and cleaner defensive shell make him a live underdog, and the Elo signal (even discounted as provisional at 3 rated fights) confirms +275 is generous.

Jones' higher striking output and meaningful wrestling activity give him more ways to bank rounds, particularly through pressure, cage control, and takedown attempts. Mederos is the cleaner defensive striker and owns strong 90% takedown defense, but Jones' pace and five-inch reach advantage should help him create enough volume and control in a competitive fight.
