Exactly HOW will that bring them on in their Speedway Career Development - Simple answer is - IT WON'T.
The National League Riders, if forced to move up at all, should be racing in the Premier League. That would make some sort of sense. As it is - Elite League Supporters are going to have to put up with their Teams being degraded (again), pay the same or more Entrance money and the National League Riders will get no chance to prove themselves against better Riders and will be absolutely murdered if they do. How this is going to help with improving a Riders ability by riding against better Riders, he can't. Perhaps in the Premier League this sort of idea might have worked - but - NOT in the Elite League.
What a dog's breakfast they have made of this.
