The relevance of the U19 addition is no longer an issue. I think the clubs have made it clear they would rather have a bye than lose their U19's. A 14th team is long in the future, two divisions would create a haves and have nots with all potential or current high performance players having to play in Div 1. The clubs have made it clear that they will not take decisive action to reduce the number of clubs, no one wants to merge, so 13 it is into the foreseeable future.
So the end result is we have a second tier competition that bears no relevance to high performance, there are numerous examples of that last year.
Fergie having two nets against the Bulls, but no he can't field at all.
Bowlers either not being allowed to bowl on Sat cause they have futures game starting Monday or only being able to bowl 10 overs.
Dalton making runs for fun in grade, it was only when he scored runs for second 11 he got a start, despite Raph's continual lack of runs.
So the GC committee have the competition they want where it is all about their club and nothing to do with their relevance to high performance or producing state and test cricketers.
The Premier League is here to stay.
