Phillies falling like flies

The Philadelphia Phillies are hovering around the .500 mark and, as such, it still remains to be seen which plan of attack they'll end up taking as the trade deadline approaches. Will they be buyers, attempting to add one more big bat in an effort to make one more run at a World Series with their veteran team? Will they be sellers, unloading the like of Cliff Lee and Chase Utley in an admission that they've finally gotten too old to compete in the long term?
