FWIW, Sonia and Daniel competed as seniors at 2023 Nationals. They finished 4th, behind Knierim/Frazier, Chan/Howe and Kam/O'Shea.
Can't help wondering if all the naysaying about their competing internationally as juniors for 2023-2024 has anything to do with sour grapes because the 2023 WJCs are such stiff competition for the other junior teams.
Sounds about like the comments that by those raising the age limit, that people were just advocating for it because those skaters were proving to be tough competition and beating seasoned/older skaters.
