How is Crawford's arm? That's a big difference maker IMO.
Toss up. Crawford hasn't played RF yet but he does pick up a lot of outfield assists, as does Werth, so I'd call that one even. I'd say the younger, healthier player is the better player, especially when the numbers are fairly even, and I would still take Werth due to his familiarity with RF, his probable desire to stick it to the Philthies, and I remember seeing him coming up in the Blo's system as a catcher way back when.
