Not that signing Salty over Pierzynski would even remotely be the difference for this year's team, but (streaks aside) Saltalamacchia has been a full win better than Pierzynski this season, and is projected by ZiPS/Steamer to be 1.5-2 wins better by season's end. This is while costing the Marlins $3M less than the Red Sox paid for Pierzynski. That's not to say that the QO would have been worth it, but 2 wins from your catcher is nothing to sneeze at.
