2008 ERAs (not that ERA is great at what it claims to measure):
Huh, Jackson had almost a one run lead in ERA a little bit ago. I wonder if it would have been possible to predict that their ERAs would move towards each other over the past month? I bet a team could really succeed by knowing what to look for in a pitcher other than a good ERA.
(I half apologize for the extra snarkiness of my commentary.)
