I've been thinking about it and although Mac's view are for the better of the game. There is a problem that needs to be resolved.
The incumbents in SL will have had more time to hold their own players. Naturally clubs lower down will have had pressure from above clubs to sell on their players. So any new club to the league would be at a disadvantage for a long period and may not survive long enough to get to a point where their junior set up matches long standing clubs.
I see no reason why there can't be a balance between the two. I would not have any player exempt from the cap completely. But newer entrants to the league could have say a higher Marquee player ratio.
So your Wigans/Saints would have the ability to have 1 Marquee player only cost £100,000 on the club accounts. They would also be allowed to have say up to 10 club grown players cost again only £100,000 on the accounts.
This encourages teams to develop their own players.
However brand new entrants to the league would be allowed say 3 - 4 Marquee players again only costing £100,000 on the cap as it is unlikely they would have 10 academy players at the very top standard.
But their Marquee allowance would drop by one player every 3 years. So by year 10, they would be at the same place as other mature clubs, developing their own players and not just buying in.
Going to either extreme gives too much to short termism or too much to the incumbents in the market place.
However, I still maintain that the overall club cap should be limited to £2million and any additional payment to Marquee player or academy grown player that goes over this £2million figure would need to come from outside the club accounts. Whether that be sponsorship, or owner payments.
So Koukash could have 3 marquee players currently. The Salford club would pay £100,000 of their wages, the rest comes from elsewhere. But the Salford club could not pay over £2million in total for the squad. In another 3 years they would be down to 2 marquee players, then 1, 3 years after that. In the mean time they would need to build up their own academy players to replace these marquee players.
