Trading Santana and Brinson (and maybe another player or 2) to Tampa for Archer (with 4 years control left) and bringing in Cain is a GREAT idea.
Cain is an upgrade from Santana defensively and offensively and would likely play CF and move Phillips to right with that arm.
Nelson, Anderson, Davies and Archer sounds pretty dang good to me.
I think both deals would have to happen to make sense.
Maybe a CF can't win a game, but he dang sure can lose one.
