With literally millions of dollar of players off-contract at the end of 2018, clubs will be looking to lock their star players (or future star players) into long-term contracts. It's inevitable that players will move clubs however there are some players that just cannot be replaced.
Below is a look at the one player your club must re-sign. This doesn't have to reflect the biggest name off contract but more-so the player I believe each club should pull out all the stops to ensure they do not move clubs.
Oates looks set for a move into the back row in 2018. Sam Thaiday looks as though he is entering the final season of his decorated career. It isn't a huge jump to assume Oates could be a ready-made replacement if the move proves to be a success.
If not, he remains one of the most dangerous wingers in the game and should be re-signed as a marquee winger. I can't see Oates leaving the Broncos but at 23 and with almost 100 NRL games to his name he is certainly going to be worth plenty on the open market.
