If Poland bring in the new rule (1 league other than Poland) quite a few of the top boys will leave, that means the Premiership will have to lower its standards inorder to maintain a competative league. One league is a none starter because there will be no way enough riders even if you went down to 5 rider teams. I think most championship teams would be willing to lower the standard(and wage costs). The exception being Glasgow and Poole, Poole I could see moving up, the standard of the Premiership wouldn't be far of their current team.
