What Would It Take for Mike Trout To Not Be the Best?
It’s November, which means it’s time for an offseason tradition: asking whether some player who had a great season is now better than Mike Trout. Is it a reasonable tradition? Not particularly! But whether it’s Bryce Harper or Mookie Betts, Fernando Tatis Jr. or (in the mind of some wildly optimistic scout) Luis Robert, the tenor of the story is the same: this one guy is a good hitter now, and so maybe he’s a better hitter than Trout, the old best hitter.
One way you could handle this pointless speculation is to ignore it. You’d be totally justified in doing so. Trout is great! He had his worst year this year, and he was still great. Thanks for raising this silly question, enjoy the offseason, see you in February.
As you might have guessed based on the fact that this is an article, however, I’m going to do a little more than that. I’m not going to get into the hot-take-ness of it all, but there are ways to examine this question with a little bit of intellectual rigor. Also, while I’ve got you here, I might as well steal whole cloth from an old Tom Tango idea and make some simplistic projections, all the better to understand our site’s more complicated projections with.
The Marcel projection system is named after a monkey, and it also doesn’t exist anymore. But the concept still makes a ton of sense. Take a player’s actual performance in the last three years, do a little weighting, do a little mean reverting, and call it a projection. That probably sounds too simple, but that’s really how Marcel works. It’s not supposed to be the best projection system in the world, merely the minimum sufficient projection system.
