Stolen from RR's most recent update, below is list of off contract players at season end.
Luke De Vere, Callan Elliot, Gary Hooper [V], Te Atawhai Hudson-Wihongi, Callum McCowatt, Liam McGing, Walter Scott, Matti Steinmann [V]
Compared to previous seasons the list is small.
Unlike with his first campaign Talay doesn't have a huge amount of wriggle room for bringing in some new players, esp young players - before the start of next season. That includes signing any of the Weenix to a full contract. There's already talk of Clayton Lewis, joining the Nix next season.
Of course Libby would free up a spot if he is sold. Plus if Fenton doesn't recover from his latest injury (though he seems determined to do so), could be a release by mutual consent
But yes Elliot, McGing & Scott would all especially appear vulnerable - given lack of game time they have been getting. That's the brutality of pro sport.
