Where he stands
Ketlen Vieira is 10-5 across 15 fights on our tape. Our rating has him at 1599 — 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 goes the distance
Ketlen rarely finishes — most of his wins come on the cards. That's not a criticism; decision fighters are often the most predictable profile on a board, because they win by accumulating rather than by landing one shot. It does mean his ceiling in any single fight is capped, and that the judges become a variable no model handles well.
Age matters more here than in most sports
Ketlen is 35. 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
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 Ketlen 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.
