The Middleweight matchup features Anderson Silva (17-7) taking on Yushin Okami (14-7).

There's a real Elo separation here: Silva at 1361 versus Okami at 1229. That 133-point gap typically reflects a meaningful difference in recent quality of competition and results.

Stylistically this is Silva's knockout artist game against Okami's wrestler approach. Silva is patient on the feet, timing counters and loading up when he sees openings, while Okami looks to close distance and put the fight on the mat. Historically these archetypes are dead-even when they collide.

A few statistical edges stand out. Silva throws significantly more leather — a 0.2 sig. strike per minute gap. Okami is far more active with takedowns, averaging 0.3 more per 15 minutes. Okami has tighter striking defense, making opponents miss more often.

The Pick: Anderson Silva over Yushin Okami. We're leaning Silva here at 66%, a solid but not overwhelming edge.
