Its hard to imagine Turner leaving the only team he's been relevant for and just won a world series with. Only way I see it happening is if he got lowballed by the Dodgers and we blow the offer out of the world.
I'm guessing the hold off has been that the Dodgers prefer to give a big 1 year deal since they have to deal with Seager hitting free agency next year, and they dont want Turner on the books during then.
I hope we don't go past 2 years on any offer because of his age. He's due to fall off any year now and a season after finally getting his first World Series seems like the perfect timing.
