Fairmount - I am not exactly sure what you meant by this. I assume you are just referring to 2025 Breeders' Cup and how few horses Cox entered last year. If so, I think he also started Stellify in the F+M Turf. So he started one on Friday and one on Saturday. Either way, as you mentioned there seems to be a trend towards fewer starters from Cox. Going into 2018, he had only had three previous starters in Breeders’ Cup races. Since then, here are his number of starters:
2018 - 4
2019 - 5
2020 - 8
2021 - 6
2022 - 5
2023 - 7
2024 - 4
2025 - 2

As you can see, two of his lowest years in terms of starters were 2024 and 2025. It seems a bit odd putting an apparently fit and healthy horse on the shelf to skip the Breeders' Cup.
