I'd take the chance and deal him. He's likely not the difference between advancing in the playoffs and not, not for this team. But NO CHANCE this happens, imo. Frankly, I'd embrace the future this year, and see what they have/need next year.....and deal Kepler for sure as part of that (maybe Santana and put Julien there?). See if Wallner is fixed or not. Get Rodriguez up here when healthy.
I'd even deal Buxton (yes, he can be traded if properly incentivized), but I can't see that either.
