If you increase SL to 14 teams then IMO you just had more mediocrity to what has been a mediocre competition for a few seasons. What has been a real success has been the very competitive top half of the championship. I would go with the SL and SL2 idea with 10 teams in each. The immediate thought is that the SL chairmen/owners will be grumbling that there will not be enough games to generate the income they want, but they have been saying themselves that they want to improve the playing standards. Having the top ten teams would ensure a difficult game every week and by definition improve quality.
The second 10 will be made up of the 2 lowest finishing super league teams and the top 8 from the championship. The teams involved will be those who have real ambition to be in SL and they should all receive equal funding.
I would have the Magic weekend as a challenge cup weekend. The reduction in the number of games will provide time for international games or "War of the Roses" fixtures.
The prospect of high quality games in SL2 would provide an opportunity for TV/live streaming deals in its own right. It would also provide for a 2 up 2 down promotion without significantly harming the quality of the competition.

And with Leeds now falling into that bottom four, they’ll get even more greedier.

Either one but not both.

Well can't argue with this

I bow down to your superiour knowledge - I was wrong. (if I am wrong I will say it)

I was convinced that it was impossible

If you are going to Batley PM me I will gladly buy you a pint / coffee - you deserve it

Have a good one

A 15 team Super League isn’t going to happen. I’d like to see a 14 team Super League, but even that is unlikely.
