Upton is one of the better young players in the game, but I'm not sure trading for him makes any sense. The asking price would almost certainly start with Jesus Montero and go up from there, probably to one or more of the Yankees top pitching prospects, a for a team that doesn't really need an outfielde cleaning out the farm for Upton isn't a wise move. And if for some reason they do end up in need of an outfielder there are two pretty good ones sitting on the free agent market.
