If they go all in on the youth movement for the position player side and add pieces to the rotation, then it probably still won't be enough to seriously contend, but might make it entertaining all year.
Get whatever you can for Smoak/Pillar/Martin/Tulo/Morales, and roll with a position player roster of Vlad (after 3 weeks), Jansen, Grichuk, Drury, Gurriel, Tellez, Hernandez, McKinney, Diaz, Maile, Pompey (if they decide to keep him), and maybe sign/trade for another outfielder to replace Pillar's outfield spot (ex. trade for an arb eligible Grichuk type that another team has given up on, or sign a vet stop gap). Use DH to rotate the young players around.
Young players means high variance. They'll need a bunch of things to go right but 2019 is a transition year anyway. Try to be as good as possible so that the timetable is moved up.
