Where he stands
Polyana Viana is 4-8 across 12 fights on our tape. He's on a 4-fight losing run. Our rating has him at 1437 — 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.
He wants the fight on the mat
Polyana lands 0.7 takedowns per 15 minutes and threatens 1.5 submissions in the same span. That's the profile the model reads first, because grappling decides where a fight happens and where it happens decides most of the rest. His matchups turn on one number more than any other — the opponent's takedown defense. Against 85%-plus defense the same fighter looks ordinary; against a striker who can't stop it he looks unbeatable.
How the model reads him
Two ratings produce a baseline, then the matchup adjusts it: who lands more, who absorbs more, who controls where the fight happens. That's the whole shape of it for Polyana and for everyone else — no manual adjustments, no fighter the model likes.
What we'd flag
Our tape runs from 2015 across UFC and Contender Series bouts, so a long career elsewhere shows only the part we can measure. And variance in this sport is enormous — one punch settles a fight the better fighter was winning, which is why nothing here should be read off a single result.
