If Byrd is the target I'd remind everyone his OPS is quite a bit higher than Jay Bruce's this year. I think it would require a real prospect or two.
Would you give up Yorman Rodriguez?
Would you give up Corcino or Travieso?
Would you give up two of Mejias-Brean, Carlos Contreras and, say, Amir Garrett? Or maybe Ryan Wright and one of those three?
Just guessing that this is the level that would be requested. I don't think the Mets would seriously expect the very top prospects, Hamilton, Stephenson, Winker, Cingrani, guys like that.
