Jack Morris is Brad Radke?
Yes, according to Jaffe, and yes according to rWAR, though fWAR has Morris at 57 wins and Radke at 46 wins.
Trying to come up with the Fangraphs number fast, we have Radke at 90% of runs allowed and Morris at 97% (or so). Morris has 3800 IP to Radke’s 2400 IP.
So, (1.25 - .90) x 4.5 x 2400/9 / 10 = 42.
And (1.25 - .97) x 4.5 x 3800/9 / 10 = 53.
That basically explains Fangraphs’ position.
(The 1.25 is the replacement level, the 4.5 is RA9 for league, the /9 is to turn innings into games and /10 is to convert runs to wins.)
What you, as the reader, has to do is decide:
1. What’s the replacement level? If you really like Morris, you’re going to put that 1.25 up to 1.30 or 1.35 or something
2. What is the performance level? If you like Morris, you’ll figure out how to put that 97% of league average down to 95% or something, and you’ll bring Radke up from 90% to 92% or something.
Then you plug in the numbers and ACCEPT THE RESULTS.
Oh, and of course, you have to figure out how to weight the various post-season starts, given Morris extra credit for his Twins post-season and much less credit for his Jays post-season. (And of course, apply the same process to Smoltz, Schilling, and Hershiser.)


Well, they’re both below Catfish Hunter (32.5) and he’s in the hall of fame. Hunter’s career ERA? 105. Same as Morris. But you sure don’t hear the righteous indignation out of the blogosphere against Catfish now do you?
To say nothing of the far lower values for Sutter or Fingers (granted they’re relievers ... but if this is about career accomplishement, well, they “accomplished” a lot less now didn’t they?)
As for the JAWS conclusion; in what world would anyone say that Morris was a lesser pitcher than Radke?? Morris led the majors in Wins for a decade. There’s not a single other pitcher who led the league in wins for their decade that isn’t in the hall of fame.
Lastly; WAR has a tendency to be an accumulator stat. If you’re mediocre but healthy you end up with a higher WAR than a better, but shorter-lived career. Pedro Martinez had a career rWAR of 73.5 while Blyleven had a career rWAR of 87.6. There is no one who with a straight face can tell me that Blyleven was a better pitcher than Pedro Martinez. I consider Martinez one of the two or three best right handed pitchers of the last 50 years, hands down. Blyleven was a run-of-the-mill starter who hung around for 20-some seasons and racked up a gazillion Ks and then suddenly, 15 years after he retired people started canonizing him as the great travesty of hall of fame voting.
Point is: no stat is all-encompassing, each has their flaws. You can’t just look at one stat and declare that player A > player B.
