Ive never understood the comparison with football, as you say fans turn out season after season even for clubs who are only making up the numbers and really have no chance of ever getting any success clubs like Fulham, Bournemouth, Burnley have next to no chance of getting top four let alone winning leagues fa cups, Palace only won their first trophy last season, no manipulation of team strengths to try to have all teams equal, but fans of the lower reaches clubs are there in numbers home and away, speedway lost that tribalism a long time ago.
