All-Rounder
VS
Silva
3-6-1
Elo 932
Striker

The Heavyweight matchup features Andrei Arlovski (23-17) taking on Antonio Silva (3-6-1). Silva will look to use a 5-inch reach edge to control distance.

Silva carries a modest Elo edge (932 to 858), the kind of gap that reflects a slightly better run of form rather than a talent chasm.

Stylistically this is Arlovski's all-rounder game against Silva's striker approach. Arlovski is comfortable adjusting on the fly, mixing strikes and grappling as openings appear, while Silva brings a versatile approach. Historically these archetypes are dead-even when they collide.

A few statistical edges stand out. Silva throws significantly more leather — a 1.2 sig. strike per minute gap. Arlovski is far more active with takedowns, averaging 0.2 more per 15 minutes. Arlovski has tighter striking defense, making opponents miss more often.
