New to online Stat and spent some time working through some of this stuff. Only to now find out it was already mostly done 15 years ago.
Anyhow interested in “professional thoughts” on what I came up with.
Basically, for the hitter/pitcher split, my impression was 50% hitter rolls, 36% pitcher rolls, and 14% fielder X rolls (hitters again, except for the “pitcherx” which I just have to ignore). This implied a $29 million (and top heavy) pitching budget. I believe the “formula” then suggests to relatively overspend on pitching?
Next, it seems like a big thing is to exploit pricing inefficiencies. I am working with older years, ‘82 and ‘86. What I have done is rank players (more in a second) then map that rank to the “slot value” for that rank. As an example in 1982 I ranked Doug Decinces as the sixth best batter. The sixth highest salary is ~$10 mil while his salary is ~$8 mil, making him a very desirable player to draft. The next iteration of that might be to sort through by positions.
For rankings I took the leap of faith that the cards would accurately reflect the underlying stats which I am now seeing is only true maybe 70-80% of the time. Those inefficiencies can only be found by painstakingly examining the cards for them especially with pitchers.
Anyhow for hitters, I used modified OPS, 1.5*OBP+SLG to approximate the sabermetric thinking of their relative importance. RC/27 might be even better but a fielding adjustment is unwieldy. Once I had that, I adjusted for fielding. For example Alan Trammell is a “1” SS, the most valuable defender, and gets 0.140 added to his adjOPS. So despite an actual OPS of 720 he winds up the #42 overall batter. The defensive adjustments are less beneficial/severe moving to 2B/CF, 3B, LF/RF/1B. Does this look about right? Catcher I haven’t figured out yet; “arm” seems to really play up versus 1-4 rating.
Pitchers did much the same, calculating an adjusted OPS allowed, and dusted off Bill James’ component ERA calculation and averaged those two ranks. Again, looking for salary discrepancies. But the pitching cards, drive me nuts, seems like many of the guys who ought to be good, are demonstrably worse than those who ought to be bad, so further understanding is needed.
Meanwhile, I’d suggest that I don’t fully understand the pitching process, or the process where relievers are called, so it might be better to spend up on what I think I do understand which is hitters.
Bear in mind this is mainly done “before” playing even one season. Severely overestimated platoon hitters for one thing, which I’m working on. Any comments or critiques to help me work out the bugs are welcomed though!
