Marlins can field an exciting, interesting team with existing talent. One thing that can be relied upon is speed. A starting lineup that would feature Sanoja, Meyers, Sanchez in the OF and Edwards and Lopez in the IF would keep strikeouts to a minimum (except for Sanchez), play good defense, and steal 20-50 bases each.
I am clearly in the minority, but I see Mack behind the plate with Fortes. Mack actually outperformed what Realmuto did in the minors at the same age.
Alcantara, Luzardo, Garrett, Cabrera, Weathers, Meyer, Snelling, Oller, Bellozo, etc., along with Perez should provide ample rotation depth even if three or four bite the dust.
