Well, you're kinda proving my point for me. The human memory is selective and often irrational. In the case of Jesse Crain and his "straight fastball" that led to losses, he was 33-21 with Minnesota (I loathe using wins but you brought it up) and had an ERA+ of 128 during his time here. He wasn't a flashy pitcher (until his last couple of seasons with the Twins, anyway) but he got the job done year in and year out. His peripherals were pretty good. He didn't give up an inordinate number of hits, his HR/9 ratio was very good, he struck out a middling number of batters, and he didn't walk an inordinate number of batters. Stats like inherited runners contribute to more bias confirmation... It doesn't really tell you what happened. If a guy is routinely thrown out into a bad situation in the middle of an inning, his inherited runners percentage is going to reflect that... and it's not an indictment of the pitcher because almost any pitcher will give up runs in certain situations unless he's dealt a very lucky hand (eg. runner on third base, no outs with the heart of the lineup heading to the plate). Feel free to continue using the stat but you should also realize it doesn't really tell you anything unless the numbers are at either edge of the bell curve.
