I can see the logic, but that also takes a lot of money and still leaves you with a SP need. I'm also a bit skeptical that the Marlins, payroll slashing as they are, would trade Yelich for Javy/Russell, who have the same time to FA and only provide marginal savings through arbitration(especially for Russell). More likely I think you would see a deal for Machado and then one of the infielders going for a controlled SP, it would have to basically be Archer or Stroman for me to be excited about the prospect. You lose infield depth when Machado leaves(especially if it's Happ going for Machado), but you also get a temporary upgrade at SS, a Darvish caliber pitcher without the dollar cost, which means that when the temporary SS upgrade(and his arb salary) disappears you can go after Harper unfettered. Machado (1 year) + Harper (increased likelihood) + Archer v. Darvish + Happ + Alzolay + Russell/Baez + remainder of Archer/Stroman package
