If the idea is that teams are to pick their own race night ‘to ensure their survival’, then that has to be the case.
However, this is what I genuinely do not understand about the one league argument predicated on teams choosing their own race nights. De Facto, that must preclude the inclusion of anyone who races in Poland, Denmark and maybe Sweden. The only alternative is to allow these riders and cover their frequent absences by r/r or guest, which would bring us full circle.
If they are to be precluded, where are all the riders going to be found for the one league?
