Well, the Red Sox currently have 11 pitchers out of options and a rough schedule to start the season to the point where Brian Johnson is expected to start the sixth game. And since most pitchers come out of the gate on pitch counts or shorter outings, the bullpen is a big factor. And even if the Sox decided to go with one fewer pitcher, that only buys time. Unless there is an injury, the issue remains.
And Leon just isn’t good trade bait. He has one year left, is one dimensional, and it does very little for the Sox to pay part of his salary and keep him on the budget if they are as concerned with the upper tax limit as they have been acting. And even then, which catcher between Leon and Swihart will get a better player back? If you were a GM for another team, which one would you want to acquire?
