Personally, I am happy that some of the folks in here who are so eager to move WMB are not in the GM's chair. He is a young player who has shown -- throughout his pro career; at every level-- the one thing needful in big-league ballplayers, and that is the ability to adjust and improve. I am fully aware that approach and plate discipline are the question: but that question has not been answered yet. If he answers it positively, as his path suggests he will, you're looking at dealing away an above-average to potentially GG infielder, with power -- the single most valuable offensive commodity in the game - who is cost-controlled. And he's playing with guys who can teach him daily about approach, the best in the game: Pedey, Papi, Nava, Nap, and so on.
My money says it comes for him. Unless someone approaches me with an appealing offer for WMB -- as opposed to the tack so prevalent here, that he is expendable -- I wait on it.
