Knockout Artist
VS
Rockhold
6-4
Elo 1302
All-Rounder

The Middleweight matchup features Vitor Belfort (15-9) taking on Luke Rockhold (6-4). Rockhold is the bigger frame at 6'3" with a 3-inch reach advantage.

Rockhold carries a modest Elo edge (1302 to 1255), the kind of gap that reflects a slightly better run of form rather than a talent chasm.

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.
