Scott Kingery is what you see when you look over your shoulder - as in, when you look back. He's not what you see when looking forward.
Scott Kingery proved to be pretty much what scouts thought, before the great spring training, before the big contract. He could not make the adjustments at the major-league level. He came up, looked good; teams adjusted; Kingery could not. End of story (or it should have been, and would have been, if not for the multi-year contract).
There are now more than a few interesting prospects in the Phillies' system. Scott Kingery is not one of them.
