I think Willingham would be worth more in trade, so I'd keep Morse.
Agreed.
That said, I don't get the folks floating the idea of Willingham as part of a Greinke deal. The Royals should not want an aging LF/DH with only one year of control. Burgess would be more useful to them (almost / rhetorical exaggeration).
I'd prefer a lesser deal for a Garza. TB would take Willingham, I think, as a DH then for picks.
With the collapse of the Adrian Gonzalez deal and the signing of Werth, all it would take right now for Willingham to Boston for Anderson etc. . . more attractive to them would be if they bow out / Lose the Crawford chase.
Finally, for LF if Willingham left, I'm thinking Damon is more attractive b/c I think he has the lefty pull pop and has leadoff skills.
