As has been said a million times, it's not up to us if we keep Josi or not, he has all the control so if he wants to stay in Nashville there isn't a thing we can do. We can't even waive him.
Saros isn't going anywhere this year unless someone just makes an offer so over the top Trotz/Poile have no choice but to take the deal. That's not going to happen, so Saros will continue to be here if for no other reason as protection both for and from Askarov. Saros is here to be his mentor, just like Pekka was for Saros or we resign him if Askarov busts but either way he isn't going anywhere. I've been following the Preds from the start, Barry Trotz is going to keep a good goalie around if he has that option.
And no Marner does not make us an instant contender. You have an injured Forsberg, Josi, Joey, and Duchene coming back and no clue how good or bad any of them will be. They weren't exactly tearing things up before the injuries to start with. We have no clue what the kids are going to do outside of that either. Even with Marner we are a bubble team at best, cause he ain't putting up 90 points here.
