From the MLBTR post, it seems that Headley would be an excellent addition for the Bucs, especially with two additional years of control.
It seems to me that acquiring Headley would meaning moving Pedro to first or shuffle the outfield. Shufflling the outfield could look like this:
According to baseballreference.com, Headley has been used exclusively at third base for the last three years. His defensive stats seem to be much better at third base than left field, where he has had 119 starts, but I am not a sabermetrics wiz by any stretch of the imagination.
I prefer trading for Headley over Josh Willingham, or any rental player, and would use him a third base and shift Pedro to first base. I would also bring up Marte after the all-star break and stick him in left field and continue some form of platoon in right field.
What do you think?
