I doubt we will see too much change from the current squad. Koirobete should not be rushed in, there are a lot of nuances to his position that would be better learnt in Super Rugby. I think we may only see Ready, Holloway, Staniforth, Morahan and Naivalu in contention. My bolter would be Jake Gordon.
I'd say Yes, No, No, Maybe and Yes. Gut feel.
