KATOH’s Top 100 List: Now Incorporating Multiple Years
Back in November, I published a top-100 prospect list that was generated by my KATOH projection system. Since that time, I’ve done some tinkering to improve the model. So even though we just did this, like, barely even two months ago, I’m back with another list for you. In addition to yielding lower AICs and R^2s and whatnot, this version also feels better in terms of the projections themselves. There aren’t as many head-scratchers as before, which suggests I’m moving in the right direction. There are still players who feel too high to me and others who feel too low to me, though I’d argue that’s not always necessarily a bad thing.
There’s still room for improvement. That will always be the case. But I think I’ve reached a point where I’ve gotten most of the low hanging fruit. This isn’t to say I’ll stop trying to make improvements, but don’t expect anything drastic anytime soon. This is the version I’m prepared to go to war with in 2016 (for now, at least). It’s not perfect, but I think it’s a sizable step in the right direction. Below, you’ll find a brief writeup of the changes, followed by a brand new top 100.
Moving Beyond WAR Through Age-28
In the past, a few commenters rightly pointed out that projecting a WAR total through age-28 wasn’t all that informative for some prospects. For a guy who’s already 25, his WAR through age-28 captures at most three years of team control, while it might capture all of a 21-year-old’s control years. In this iteration, I made my output a bit more flexible. For players 22 and younger, I still forecast WAR through age-28. But I expanded my horizons for players 23 and older, and now project the next six years. So 23-year-olds get a WAR thru 29, 24-year-olds get a WAR through 30, etc.
