The Yankees and Dodgers are doing exactly what MLB wants them do to, become mediocre, then rebuild. In fact, the same can be said about the Sox and the 'Stros. They were mediocre (or worse) got the draft pics, then rebuilt.
By "mediocrity" I meant parity with the average of all teams being mediocre over a period of years.
But you're much more "cerebral" than we Red Sox fans, so you already knew that.
