Agreed, his value has dropped through the floor and you probably don't get much back for him if you move him coming off that season.
To me, the Yankees looked like a defensive liability out there in the playoffs. Sanchez, despite the arm, is an absolute liability behind the plate. Volt can't scoop a ball at 1b's. Andujar, God Bless him, has issues throwing the ball. It's just too much to hide, too much to expect you can get away with it, in October, against the very best teams. They have to get better defensively.
Sanchez really fell off a cliff offensively when they took Sonny Gray away and started to nudge him towards DH. The kid has so much talent but is an enigma. How can he not know that he has to keep the left shoulder down on outside pitches and take the ball to the opposite field? So painful to watch him, AB after AB, trying to pull breaking balls from RH pitchers, miss by three feet and end up with his head looking at the opposition dugout. Doesnt get better behind the plate. Seems uncoachable...
