Assuming the Sox sign one of the OF'ers that have been mentioned (Kemp, Either, Shoo, or Granderson), as well as Drew, I think all of these guys are expendable. But, would it be enough?
JBJ, Middlebrooks, (Nava or Gomes), Lavarnway, and a minor league pitcher.
Undestandably, we would have to probably deal Nava over Gomes. We may even have to sweeten the deal by offering Vazquez or Swihart (we don't need both of them) over Lavarnway. But, I would think that should get it done and not really hurt us.
JBJ would be expendable with the siging of another OF'er and the addition of Stanton. Middlebrooks would be expendable with Gecchini(sp) just around the corner. We can put Xander and Drew on the left side of our infield for the upcoming year. We don't need 2-3 catchers. Then add a minor league pitcher and Nava or Gomes.
