Wouldn't it be considered a restraint of trade? For instance if the Broncos decided that their time, expertise and money into Fifita was worth some ridiculous figure, let's say $700,000 how could the Titans hope to afford that and the $1.3 Million contract?
It doesn't even have to be Fifita, what if a club like Sydney just stock-piles talent and if you want Robert Toia for instance it's going to cost you as much if not double his salary?
We've seen how teams have 'managed' the salary cap, you're going to tell me they're going to be honest with transfer fees?
