I for one will not lose any sleep if Mateo leaves. As for Finch I don't care either way but would have to say he would be better outside Smith than Green would be. I know I've said it in other forums but green and Smith are too similar in style.both are slow. At least Finch can sniff out a try - but both he and Smith are found wanting in defence - you can hide one but not two.
I hope we don't fall in the trap of relying on our juniors, I saw what that did to us in the early seventies and again in the late eighties. From what I have seen if a young player is going to make it he forces his way up to first grade within two seasons at most. Most of the names being bandied about like Hauraki, Oake, Mateo, Taia etc have been around for a few years now and are good PL players but not exactly looking like world beaters. I can't see any of that bunch making permanent first grade.
