It remains to be seen how much, but unfortunately for the tahs a quarter of the 23 from that game (Tupou, Leota, Sinclair, Foketi, Vailanu, and Edmed) look to be gone, along with this years best 2 performers (Bell and Gleeson). Another 4 of that 23 (Barrett, Adamson, Bowen, Lancaster) also appear to be off contract, though I'd expect most of them to re-sign.
Lancaster will be tricky though, that was his best game in sky blue by a long way, but re-sigining him would lead to a pretty imbalanced back unit and likely mean a fair bit of the salary cap was going unused each week.
