His worst season was clearly abused. he has the right # of IP, but based on his other stats I'd say he was burned early in the season or during a stretch run and pitched all his IP back to back, or relatively close. I find performance history to be relatively useless for low IP pitchers (less than 180 IP/162) with more than 3 uses as you don't have enough info to determine how they were used and you have too much info on how they performed. I'm still on the fence for performance histories for hitters. It's just really, really, easy to have the data skewed by a handful of poor seasons, and the worst seasons may not show up due to the worst being rated by ERA. I's quite likely you had several uses of Northrup that were much worse than the one listed that had ERAs below 7.
I abuse the low IP starters all of the time. Take the 1932 Wilcy Moore. RL BB/9 2.16, BB/9# 2.04, BB/9 of 167. Performance history average of 3.98. He only has 10 uses (at least 6 of those by me) and his worst season BB/9 is a 12.55 (that was also me - I started him in 4 straight games to open the season. And then, during the stretch run to rest the rest of my staff, had the 200k Bill Bishop as my only starter with Moore set up as my only useable RP so that once Bishop got injured in the 2nd inning Moore would throw the rest of the game. I got 12 or 13 consecutive games out of him that way where he threw 250+ pitches but never more than 8 IP. He was WELL OVERUSED (especially since fatigue is based on pitches, not IP). So, while he exceeded his RL IP by only 11 IP (41%), he exceeded his PC by probably close to 800%. There is no wayto know how many such uses of Northrup exist that skew the data majorly. I know I've used Northrup and Cisco Carlos that way several times each with fatigue teams that were on the cusp or that I under-calculated IP on. Or whenver I've felt that a pitcher was my best abuseable option to rest the rest of my staff for the playoffs or to recover from fatigue management issues.
With Northrop, we're talking about 387 OL seasons...that's a huge sample size, plenty large enough to cover for some misuse, which has obviously happend, as it has with almost everybody.
In the Wilcy Moore example, your wacky seaon represents 10% of his total use, and if you misused him every time, that would actually be 60% of his seasons. For Northrop, it would equal 232 misused seasons, which I highly doubt is what has happened in his case. Note that Northrop's era over those 387 seasons is 2.85, further evidence that the high bb/9 numbers are not the result of misuse.
(It would be good if the WIS showed both mean and median averages in the performance history.)
In addition, as this thread highlights, there are several pitchers performing similar to Northrop. There's no way they are all being abuse in 60% of their seasons.
