Bautista isn't/won't be part of the core for 2018. Donaldson and Martin are still elite, the other two are sunk costs though so I agree there. The team really isn't in all that bad of a position. Alford and Teoscar should be ready for the show by next year, maybe Tellez turns things around, maybe he doesn't; Gurriel, SRF, Danny Jansen, Ryan Borucko, Reese McGuire (?) could all be knocking at the door for role-playing time at least. It's highly unlikely any of these guys will impact the team like a Devers or Gary Sanchez, but that's still a good amount of young, potentially not useless talent to complement the likes of JD, Martin, Stroman, Sanchez (not sold on him yet), Osuna and maybe Travis.
I think the FO aren't in as big a pickle as one might think. The Red Sox will be the team to beat in the East and it won't be close, but there's a lot of uncertainty in the rest of the division and the potential wild card teams. Playoffs are well within reach, the biggest obstacle will be securing depth for both starters and position players.
