Not sure,but is not the case that GSA is used for Team Building but rolling averages kick in when season starts ,to stop average fiddling during season.
While I am also surprised ,but reckon they have got it right.Ambition in speedway is knocked on the head by the powers at be most of the times with their rule book changes from year to year.
Think Ostergaard on good equipment(which I imagine will be part of the deal)is still a decent signing.Good back up to Cook and Wells.
Feel a bit for Vissing,good season and fans favourite but averages probably the only reason he was ruled out.
