Certain clubs will need to rejig for lost attendances but it won't be anything major, a player or 2 on less than usual or a player less in the squad, certainly nothing that closes the gap between the SPL and SFL.
I do hope the SPL clubs don't look for much from Newco attendances when they arrive up there, I would think most Newco fans wouldn't like to give a pound of their cash to the SPL clubs in the future.
