Edwards: The worst teams in baseball history

From Craig Edwards at FanGraphs on November 15, 2019:

After the World Series ended and the Nationals emerged victorious, I wrote about how the Astros had put together one of the greatest regular seasons of all time and joined the (perhaps ignominious) list of great teams without a title. In doing so, I created the below graph, which shows team winning percentage and WAR, highlighting some of the greatest teams of all time.

At the time, I didn’t mention the teams at the very bottom-left of the graph. If the teams at the top-right are the greatest, then the teams in the bottom-left are the worst. In trying to find a single number to determine just how good or bad a team was, I created an IQ-like score for both winning percentage and team WAR, where 100 is average and every standard deviation away from the mean was worth 15 points. Then I took the average of the two scores for one final number. For reference, this year’s Astros team ended up at 136.5; more than 90% of all teams from 1903 through this season were between 75 and 125.
