It remains to be seen if that is what the Sox have. One 4/4 night does not mean that Vas has learned how to hit well enough to play a big chunk of the games. Yeah, his D and game calling may be very good but is that enough if he is a low ave low OBP guy?
Leon may be closer to a complete package than anyone saw before he was acquired. We don't know that yet, either.
Who knows if they will not skip a beat.
