I think its looking like Werth may be closer to the Sox's agenda right now, actually. Between Crawford and the 6 outfielders the team has, only Mcdonald and Cameron are righties. Some are wary of Werth, but he has strung together 4 great seasons, with great RHH power, and decent speed. Plus he'll likely be a bit cheaper, replace Drew in RF well, and the team has already expressed a good amount of interest toward him. Crawford and Ellsbury fill similar purposes, and will create a L-L matchup in the very beginning of the lineup, and displace the team's laser show MVP.
For all purposes, I think Werth is much better suited for the team right now.
