TBH I don't know if I think Nathan changed the men's field in the US as much as he is the logical conclusion of men's skating worldwide, or at least what men's was before 2018-2019. If anything, I think Jason is going to be more of a trendsetter after his performance at Worlds 2019.
He may have faltered in the FS, but he got SECOND in the SP without a quad. Now, that's not to say I think men will only go for PCS/SS/Spins/Steps in the future, but I think the reality is that the vast majority of male skaters, even those at the top right now, will only have one or two consistent quads. Jason's performance shows that those men who can only get 1-2 consistent quads have hope to compete with the Nathans, Yuzus, Jins, and Chas if they make everything else excellent. I would think that will inspire more men to stay with it and work on more than just jumps.
