Those stats really don't show me much. So you think allowing more ER than strikeouts may be a result of bad luck? How do those stats not show you that those pitchers suck. You can maybe forgive Cook a little bit for a Coors inflated ERA but the others have no excuses. I would like to see the ERA, WHIP, and FIP for those pitchers over that time. Fangraphs wont let me easily get the FIP for a portion of a players career, so FIP listed are the "average" based on my judgement.
