Well of course they are...!
It's because of the business model they use, ie costs exceed income...
Teams spend 'big' money on trying to be successful and when they achieve success they cannot afford it, and the supreme irony is that this success is virtually worthless in relation to more media coverage and increased revenue because hardly anyone in the respective towns/cities know the sport even exists!!
Quite simply a successful team who wins a national title makes approx (at best) 1000 people feel good about themselves at most tracks.
Therefore is it really worth the effort of bringing over foreign riders, paying air fares, hotel bills, providing workshop facilities etc etc to win a trophy that hardly anyone locally will even recognise never mind take any civic pride in winning?
Your local ice hockey team doesn't have players that play in the NHL one night, in front of 20000 plus crowds, and get paid 1000's of dollars, and then come over here to represent a British team in front of a couple of hundred spectators, yet Speedway actually makes this 'the norm' by paying world stars who ply their trade in their own countries £1000's in salaries, flights, accommodation etc.....
Simply Speedway has reached its nadir, and it is now reaping what it has sowed for so many, many years through the failure of those who run the sport to take their collective heads out of the sands and deliver a product which is consistently entertaining, value for money, and governed by a set of rules that are both simple for the fans to follow and credible to the wider outside watching sporting public and media....
No doubt those who 'run' the sport in this country will believe that the weather, the euro's, the olympics, the paralympics and even people staying in watching the soddin' mars landings are the main reasons why 'another 200 or so' decided not to go to speedway each week this year...
Because let's face it, the reason speedway's crowds are dwindling and the sport is dying on its arse isn't their fault is it??
