It depends on what role he believes he can play in 2018.  If he wants to play regularly, then he needs to look to the AL for a team to sign him as a DH that only plays LF sparingly.  If he wants to be the 5th OF here and a RH bat off the bench, then I'd welcome his leadership and experience.  I think he could still be a decently productive bat as a pinch hitter.  I seriously doubt that is what he wants though.
