I have been thinking about this for a while and I think this is the best move to make for the Phillies.  Vic is still fairly young and inexpensive and has reached his likely peak value...ever.  All-star with an OBP above .370.  You move Werth to center and then use one of your young OF's to fill in.  I think this is what smart teams do in terms of getting the most value from their players.  I won't kill the Phils for not doing this as it is easier to put Vic out there and hope for the best.  I think what you could get for him and prospects + playing Taylor or even Mayberry is more valuable than what Victorino brings.
