Buyer's guide: Outfielders

As I have in previous years, I'm going through position groups to provide a look at where teams will find value (and where they won't) in free agency this offseason.

Here's a look at best values, worst values and trade targets among free-agent outfielders.

Best values

Curtis Granderson, OF (Free-agent ranking: 13): Granderson may never again be the hitter he was in 2011, but the hitter he was in 2012 was pretty good, too, and if he's asked to play left field rather than center, he should be back to 4-WAR (wins above replacement) territory.
