If they are seriously offering him a contract in that neighborhood he's not turning it down. He'd be insane to do so, regardless of how he feels about winning a title. Besides, The Marlins have two championships in the last two decades. If Stanton stays put and they lock up their young talent (Fernandez, Yelich, Hechaverria), it's an indication that Loria is ready to spend again. Sure, he'll probably blow it up again down the road, but the idea that the Marlins never spend isn't really true. Loria will take a shot at a title for a few seasons and win or lose, he'll hit the reset button again.
At that point, if Stanton wants out, he'll waive his no trade clause (because yes... he's getting one) and they'll work something out with a big market team that can take on the majority of his contract.
