Good question. By step aside, I mean, if they are unwilling to adopt the need for change, instead using their position within the BSPA to keep things as they are and thus hold back or deter new thinking by ambitious and visionary promoters. Then by all means stay in speedway, but run a team on a semi professional basis in a more suitable league.
As for Sheffield, as with any promotion, if the numbers don’t stack up to make it viable in the medium term for current or potential owners, then there is little hope for their long term future.
one of the issues Sheffield have is their stadium availability and more so the unavailability of the back straight terracing which severely restricts the possibility growing attendance & associated revenue.
