The Featherweight championship matchup features Jose Aldo (14-9) taking on Chan Sung Jung (7-5).

There's a real Elo separation here: Jung at 1643 versus Aldo at 1541. That 102-point gap typically reflects a meaningful difference in recent quality of competition and results.

Both fighters land in our "All-Rounder" archetype — fighters comfortable everywhere, able to strike or grapple depending on what the opponent gives them. When mirror matchups like this happen, the edge usually goes to whoever can impose their preferred pace and range.

A few statistical edges stand out. Jung throws significantly more leather — a 1.3 sig. strike per minute gap. Jung is far more active with takedowns, averaging 1.9 more per 15 minutes. Aldo has tighter striking defense, making opponents miss more often.

The Pick: Jose Aldo over Chan Sung Jung. The model gives Aldo a slight nod at 63% — this could easily go either way.
