With the signing of Trevor Bauer on Friday, plus the expected return of David Price, the 2021 Dodgers rotation that includes Clayton Kershaw and Walker Buehler will, on paper, be one of the franchise’s best ever. How will it compare with great Dodgers rotations of the past?
A good way to compare rotations from different periods in baseball history is to use the ERA+ stat. What that does is compare an ERA to the league average ERA that season and convert it into a number. If a pitcher or team has an ERA+ of 100, then they are exactly the league average.
