Nah, the salary cap has worked well when it was properly applied. We've had crowds doubling since the beginning of SL and that means more money all round.
Anyone who seriously thinks that the salary cap was the cause of Paris or Crusaders demise needs to read up a bit. Those clubs were doomed no matter what. Dropping expansion clubs with insufficient funds into SL and then expecting the Salary cap to save them is stupid.
It's also given clubs like Warrington and Huddersfield a new lease of life. For years they could not beat St Helens and Bradford respectively, now look where they are. See what a lack of salary cap has done to soccer.
The problems are:-
a) too many teams in SL reducing the TV money for everybody
putting expansion sides into Sl when they weren't ready
c) a failure to relegate clubs that are obviously struggling
Very seletctive with Paris and North Wales, what about the others I mentioned ( oh and I missed Bradford)
The salary cap isn't working, it's not stopped clubs going bust, when 8 teams ( more than half the league) have go into administration then one of the reasons for it is blown out of the water.
Both Huddersfield and Wire are competitive due to wealthy backers. I'll claim that the salary cap is allowing Saints to compete at the moment
