A club can't sign someone from another club and make them a marquee player. That's one of the rules.
I think they need to be at the club for 2-3 years before they can then be a marquee player
The other marquee spot is only for players brought in from outside of the premiership.
The only way I can see the CVC money being used for players salaries is this:
1) if the club is currently operating well below the salary cap and don't have the funds to safely spend up to it, then in theory the CVC money could be used to increase salaries or bring new players in until the cap is reached.
2) sign a high profile high quality overseas player and give them a massive salary - similar to our signings of Kurtley Beale, Charles Piutau
however, you can only have one of those.
3) If a club has an outstanding talent in their squad that they wish to retain, they could pay them significantly more than they're currently getting and make them their non-overseas marquee player.
This would mean that whoever is currently marquee would come under the cap.
for example, if we assume that Launchbury is currently our marquee player and is earning £400k per year (pure guesswork), then, if we wished to offer Daly £600k to keep him, we could, but Launchbury's salary would then be part of the cap.
Options 1 and 2 aren't sustainable if just using the CVC cash to fund it, and option 3 is a delicate balancing act.
Providing the cap doesn't change over the next couple of years, the CVC cash shouldn't make its way to the players too much
