So it's completely pointless then because what Wigan can't do is prevent the player form talking to other clubs
once he's spoken to Wigan.
No player is going to just listen to what Wigan put on the table and the term "first refusal" is misleading. It makes it sound as if Wigan offer him a deal he is contractually bound to take it which is not the case.
It's just another one of those silly terms IL is fond of using when Wigan lose a player to an NRL club to make it sound less painful but in reality is meaningless.
Even without "first refusal" any players agent would be talking to Wigan anyway but they would also want to listen to offers from several clubs so in reality it makes zero difference.
