That's what I was doing - going by age. If Taylor was at his best in 2022 and 2023, Yazdani potentially still has years to reach a new peak. When your peak is best in the world and your trough is second best is the world it can be difficult to tell the location of the actual peak.
The other argument in favor of Yazdani over Taylor is that Taylor had a very limited prime and all these head to head matches all happened during Taylor's prime which skewed the head to head record in Taylor's favour. If Taylor and Yazdani had met each year from 2015-2024 the record could be more even. But when Taylor wasn't good enough to compete with Yazdani he was either not on the team or retired. If Yazdani had taken a couple matches off Taylor before his hit his prime or after he started to decline it would change the head to head perception significantly.
All in all Taylor was only undisputedly the best in the world three for years 2018, 2022, and 2023. Returning to the OP topic if Yazdani wins this year then Yazdani was the best in the world 2016, 2017, 2019, and 2024. Multiple Olympics, multiple weights, and an age level title too. It might be enough for some. He'd probably need one more still to pass Taylor in my estimation. If Yazdani goes on a run of 4-5 more titles it really isn't debatable and he is one of the greatest freestyle wrestlers ever. All Taylor did was block him from being universally seen as the best ever.
