I have to disagree with that a bit, there are several teams in Sweden that have several local riders in their squad.
Like Smederna who have Zetterström,Linus Eklöf + a bunch of younger riders, Masarna who have Lindbäck, Anton Rosén, Linus Sundström,
Piraterna have Jonas and Daniel Davidsson, Vetlanda have THJ and Peter Ljung, Rospiggarna have Andreas Jonsson, Lejonen have Oliver Berntzon...
Does this means that Swedish speedway is flourishing? It does not. On the contrary it has allot of problems and local riders itself doesn't mean
that the attendances is sky rocketing or anything like that.
