Under 62%Over 38%

The Middleweight matchup features Vitor Belfort (15-10) taking on Luke Rockhold (6-5). Rockhold is the bigger frame at 6'3" with a 3-inch reach advantage.

The Elo gap here is razor-thin — Belfort at 1440, Rockhold at 1419. On paper, this is as close to a coin flip as it gets.

Stylistically this is Belfort's knockout artist game against Rockhold's all-rounder approach. Belfort is patient on the feet, timing counters and loading up when he sees openings, while Rockhold is comfortable adjusting on the fly, mixing strikes and grappling as openings appear. Historically these archetypes are dead-even when they collide.

A few statistical edges stand out. Belfort throws significantly more leather — a 2.0 sig. strike per minute gap. Rockhold is far more active with takedowns, averaging 0.0 more per 15 minutes. Rockhold has tighter striking defense, making opponents miss more often.

The Pick: Vitor Belfort over Luke Rockhold. The model gives Belfort a slight nod at 62% — this could easily go either way.
