I hate to say it, but as a Storm fan I think it is time to let Slater go. Let some desperate team pay big cash for him and free up some salary cap. I think he is still the best fullback in the game but really he is in decline, slower, more inconsistant over the course of the season and his attempts at playmaking (maybe auditioning for a 5/8 role) have been terrible. Either that or just rest him for half of the season and just play the big games while letting some young guys have a shot at fullback. This year has just been too long for him, recovering from a shoulder injury then world club challenge, 26 week season with origin and a world cup to come.
As for the rest of the team I would have replace O'Niell with Fonua, despite all his stupid errors he hits the ball up hard and often gets a fast play the ball this can really get a you rolling early in a set. Also the forward pack has no go forward early in the game, I actually think George Rose will be a massive help next season. Widdop was really average during the finals just too long out of football to be thrown into a tough finals game, Hampton shows potential and that QLD cup guy is meant to be a gun so I think 5/8 is not a worry for next season.
