The thesis keeps the winner and the method separate. Winner: Ismail Naurdiev, by a slim margin. Their most recent decisions don't separate them: per the official cards on MMA Decisions, Vettori won only round 3 against Ferreira on all three cards, and Naurdiev won round 2 against Park on all three cards before the two-point deduction, which would have made it 29-28, 29-28, 29-27 without the foul. Over the rounds, what separates them is the net of their UFC striking numbers, and it points to Naurdiev: 53% accuracy and 65% defense against 46% and 56% on UFC.com, and 1.7 significant strikes absorbed per minute against 4.6 on FightingData. Vettori lands more, 4.74 to 3.66, but on FightingData the gap between landed and absorbed is about +0.1 per minute for him and about +2.0 for Naurdiev. These are total-fight-time rates, not stand-up exchanges alone: FightingData logs 16:49 of Naurdiev's own control time in the UFC, about 18% of his 91 minutes, which lowers his absorbed rate and changes what accuracy and defense measure, while Vettori's control is only on record for his last three fights, 1:08, 1:17 and 0:00. The other caveat covers all of Naurdiev's numbers: seven UFC fights, and his four welterweight bouts from 2019 and 2020 make up 60 of roughly 91 minutes against opponents who weren't checked, while Vettori's rates include Adesanya, Costa, Whittaker and Cannonier. That could shrink the gap by an unknown amount, so the edge is small, not zero. Wrestling and cardio don't tilt either way. Recent opposition doesn't separate them either: with no ranking for Ferreira or Park on their fight dates, and Ferreira three pounds over the limit at catchweight, the Ferreira/Park comparison leans nowhere. Dated opposition is Vettori's best argument: between 2021 and 2023 he fought Adesanya for the title, Costa at No. 2, Whittaker when the two were the top two contenders, and Cannonier at No. 4, and in July 2025, still No. 10, he lost 30-27, 30-27, 29-28 to the 11th-ranked Allen; fight-week previews show no ranking for Bruno Silva, Park or Loder, and Naurdiev's welterweight opponents weren't checked. That's a qualitative read with no verifiable discount on Naurdiev's numbers, and it isn't enough to cancel the measured gap. Vettori's durability speaks to the method, not to rounds won. The Dolidze rematch doesn't decide it: the official cards have Dolidze winning rounds 1 and 2 on all three cards, which rules out duration as the explanation, but it can't separate decline from 21 months of ring rust or from changes in Dolidze; it counts as uncertainty. Age, 30 to 33, has no mechanism tied to performance in this research. Method: decision, because Vettori has never been stopped in 30 fights, three of Naurdiev's four UFC wins went to the cards and his only UFC knockout was an 86-second finish of Loder. That explains the method, not the win. It falls apart if Naurdiev's accuracy and defense don't hold up against someone at Vettori's level, if the Italian finishes takedowns and pins him on the fence the way Park did in round 3, or if Naurdiev fades and gives away points on fouls like he did in that fight.

1. 01

   If Vettori finishes takedowns and pins Naurdiev on the fence, the way Park did in round 3, the striking stops being the center of the fight and it swings to the Italian.

2. 02

   If Naurdiev's accuracy and defense don't hold up against someone at Vettori's level, the measured edge, which comes from a thin sample, disappears.

3. 03

   If Naurdiev fades in round 3 or commits fouls that cost points, as he did against Park, his thin margin on the cards is gone.

4. 04

   If Vettori out-lands Naurdiev and eats less in the round 1 exchanges, or if Naurdiev's accuracy drops once he's pressed against the fence, the measured edge in the striking numbers, which is the whole basis of the pick, doesn't show up in the fight.
