I think we can almost guarantee it...
In the Speedway Star, Matt Ford mentions how those previous generation of promoters basically left a very poor legacy, and when the going was good, they didn't invest money back into the sport, and today's promoters get all the blame and stick from fans for the current malaise...
Ford is someone I do have a lot of respect for but the previous promoters haven't watched over the last ten to fifteen years or so worth of unchecked decline have they?
They didn't make "DU'ing" so fundamentally important, nor run Guestfests after Guestfests, nor indeed just pick and choose what league to race in whenever the moment came along to suit themelves..
And. Instead of "going it alone" when the GP's and Poland took over, they instead pandered to others and let their own operating model become defined by these outside influences...
The result? Team Speedway in the UK simply isn't an authentic product to sell, which then hugely impacts its relevance, and therefore fan engagement. .
This winter's goings on is just a "new way" of making the sport look the way it does, no doubt there will be other ways to keep the same reputation in the future...
