Look, I adore Nick Swisher. There are few things on this earth more compelling than watching someone who absolutely loves what he does for a living and takes such joy in his life. I love watching Swisher for the same reason that I enjoyed watching Luis Sojo—he's just having fun, and it's infectious. (As an added bonus, Swisher is an actual useful everyday baseball player, as opposed to Sojo, who always felt like he walked in from a neighborhood softball game by mistake, and often hit like he was in one.)
But there are several reasons why it's probably for the best that the Yankees did not sign Swisher to a long-term deal.
