I feel that the three big trade names out there will be Stanton, Upton and Morse in that order. Morse is the cheapest and least team controlled. He is 31 and is a competent bat with horrible defense in the outfield and likely league average at 1B. Upton can have Morse's bat, but plays the best defense in covering the most ground. Stanton has the best bat in the game IMO and has a heck of an arm in RF and he moves fairly well for a guy his size.
A Stanton trade is a haul for the Marlins and upends a minor league system for the other team.
An Upton trade is cleaning out some top prospects.
Morse is one good prospect and a serviceable MLB guy.
Teams that whiff on Stanton or Upton should see Morse as at least a cheap solution for a quick bat add.
