Yes, the Playoffs Are Still a Crapshoot

We live in an era where every team, to some degree or another, embraces modern analytics when assessing itself and the rest of the league. Wanting to know about the numbers that drive baseball has filtered into fandom as well, which is why you’re here on this very website! But despite all the progress the stathead crowd has made over the last quarter-century, when it comes to the playoffs and playoff results, many fans seem more inclined to defenestrate the numbers and attribute the losses to all sorts of causative elements beyond a surplus or dearth of players just happening to have particularly good games that week.
In the worst case, failing to win two of three games or three of five is attributed to some kind of character flaw. At best, the loss is because of some fundamental flaw in a team’s construction, typically something that sabermetrics is to blame for, no matter whether the team is sabermetrically inclined or not. Here’s one example of very common thinking along these lines just from the last couple of days. It’s from a fan on Reddit, so I’m not specifically attributing them, mainly because I don’t want to risk social media pile-ons:
The postseason is the real season from now on, so the focus shouldn’t be on sabermetrics as much as it has been. With the playoffs being expanded, 111 wins doesn’t mean squat. Shift some of the focus to bringing in guys who play with fire and aggressiveness and will situationally hit rather than live and die by the long ball. If it costs us some wins during the regular season, so what?? It’s the little things that win the most important games.
With three of MLB’s four 100-win teams already out of the playoffs and the 99-win team pushed to the brink but ultimately surviving, these types of incriminations will be common this season. The Dodgers didn’t lose a 60/40 matchup (the ZiPS projection for the series) because they were simply outplayed over four games, but because something was broken in how the team was built. Depending on who you listen to, you can hear the same type of grumbling about the Mets and Braves.
Since questions should be explored rather than dismissed, let’s look at playoff overperformers and underperformers over the Wild Card era (starting in 1995) and examine if there really are consistent patterns behind which teams are overperforming or underperforming in the postseason. And since this is illustrative more than anything, I’m trying to keep it as simple as possible, within reason. Read the rest of this entry »
