I think that Lugo will get looks from many teams if he in fact is DFAed. He may not be worth $9.mil/yr. to the Sox, but would seem a decent investment at the Veteran Minimum. By all appearances, he can still hit.
And I believe his range MAY improve if his knee continues to heal and get stronger.
At the same time, I would not be surprised to see the Sox DL him at least until they have a good indication of what Lowrie and Lowell will bring.
