Probably that they go back to pitching well. Just a hunch. It's pretty funny how high people got when we had like 5 of the best 20 starters in baseball, but then when the inevitable regression happens - albeit rather annoyingly in a terrible 3 week stretch - people lose their minds. Did you really expect Lester to maintain a sub 2.00 ERA or Hammel to not turn into a post-June pumpkin? People have trouble wrapping their heads around it because it inexplicably happened to 4 of the starters at the same time and not just went from giving up 1-2 runs a game to 3-4 runs. They went from 1-2 to 5-6.
