Well, if Davey didn't know, that's bad, and if Davey knew, that might be worse.
Last year. his OPS bottomed at .517 on May 8. It got up to .738 on July 25, dipped, and peaked at .745 on 9/6. It ended the year at .717, which tells you that his last 24 games were bad enough to poison the first 136 enough to drop .028 OPS points. I'm not going to do a calculation for that last stretch.
