Where he stands
Demian Maia is 9-5 across 14 fights on our tape. He's on a 2-fight losing run. Our rating has him at 1621 — it moves with every result and weights who he beat, so a win over a ranked opponent counts for far more than one over a debutant. A record on its own says very little in this sport — two fighters at 12-3 can have faced completely different opposition, which is exactly the gap the rating is built to close.
No single dominant tool
Demian's rates don't point hard in any direction — 1.8 strikes landed a minute, 1.9 takedowns per 15, 38% takedown defense. That's the most common profile in the sport and the hardest to project, because the matchup rather than the fighter decides which skill ends up mattering.
Age matters more here than in most sports
Demian is 48. MMA decline tends to arrive suddenly rather than gradually — durability goes before output does, so a fighter can look sharp on the stats right up until he doesn't. The model factors age in, and it's one of the places we'd trust the number least on any individual fight.
How the model reads him
Demian's rating updates after every result and weights the quality of the opponent. Against a specific opponent it becomes a win probability, adjusted for the stylistic matchup — striking output against absorption, takedown rate against takedown defense — plus age and layoff. The weighting is ours; the output is published on the fight board and graded.
What we'd flag
The tape starts in 2015 and covers UFC and Contender Series only, so career records elsewhere aren't reflected. Beyond that: MMA has the highest single-event variance of anything we model, and no rating survives contact with a flush shot.
