I too am referring to overall value. Defense is part of overall value. Even if Lake outhits Castro the rest of the way (not a guarantee), he will be a worse defender and the overall value could easily be less than just sticking with a still crappy Castro. I cannot imagine they moved him off of SS "because of Castro". If a guy can play SS, he is inherently more valuable than the same guy playing LF. He began his pro career at SS but was moved around to other positions almost from the beginning.
