Misleading in that it implies their pitchers haven't pitched well, but the reality is far more nuanced than that. It's just kind of a hard thing to do not only because it's difficult, but you just don't get that many cracks at it. The elite guys end up traded, your hook is much shorter in October, and for the starters they pretty much need a series victory to even get a second start.
Between 1983 and 2017 the Brewers made the playoffs twice. Hard to get multiple playoff wins that way.
This statistic truthfully is mostly limited by the years 2018-now. It's not as jarring when you look at it that way.
I would ask how many teams have 3 different players with 2 postseason wins since 2018? Maybe a handful?
