Well I agree to disagree
I am confident the future will tell that it is the right option. I am firmly against a new european cup. We do not need more and more matches in the agenda. We need one top European competition, as the Super League was initially intended to be. Maybe a second one with the Championship. I must say I am not too much in favour of licensing myself. I think that it removes lots of the interest of lower leagues and gives an unfair advantage to lower teams of the higher competition who can get a rent for several years even in case of poor results. Hopefully, eventually the higher competitions will not be closed. At least I hope that there will be P&R every 2-3 years, I would hope it would be more often. In any case licensing and europeanisation are not logically linked.
Regarding the Cup, there is already a European Cup with the Challenge Cup which is open to clubs from the coutries in Europe playing RL. It would have no history, would be dominated by English clubs like the Challenge Cup and would be pretty much a meaningless addition to the Challenge Cup.
Anyway, my prediction is that in 10 years, Leigh will be playing in a great European Championship with more supporters and more TV coverage, be it SL or the Championship. This is something who would not have happen if the RL had stayed focused on an M62 competition.
