ERA+ is a flawed stat? Ok. FIP isn't. Walks, hit batters, strikeouts and home runs allowed. All it looks at. It completely eliminates the strength of the defense behind you.

Sandy Koufax 1961-1966 2.16 FIP
Clayton Kershaw 2011-2016 2.26 FIP

And the other stats...

ERA
Koufax 2.19
Kershaw 2.06

WHIP
Koufax 0.970
Kershaw 0.908

K:BB ratio
Koufax 4.16:1
Kershaw 5.62:1

And again, Koufax had a bigger strike zone, and a 15", not a 10" mound.

Average NL ERA
1961-1966 3.65
2011-2016 4.19

Spread
Koufax 2.19 ERA, league ERA 3.65, spread -1.46
Kershaw 2.06 ERA, league ERA 4.19, spread -2.13

Before Koufax began his peak run in 1961, he pitched from 1955-1960, totaling 103 games started (174 appearances, in total), throwing 691 2/3 innings. He had a 4.10 ERA, a 100 ERA+ (league average), and a FIP of 3.94.

Before he started his peak of 2011-2016, Clayton Kershaw pitched from 2008 to 2010, totaling 83 starts, throwing 483 innings. He had a 3.17 ERA, a 126 ERA+, and a FIP of 3.32.

In his second season, 2009, Kershaw was 8-8 in 30 starts. He had a 2.79 ERA in 171 innings of work, striking out 185 batters, had a 143 ERA+, and a 3.08 WHIP. His 6.3 hits allowed per 9 innings pitched was the best in baseball. His 3.08 FIP was the 5th best in the National League.

By his second year in baseball, after only 21 starts as a rookie, Clayton Kershaw was an elite pitcher.

1961, the first year Sandy Koufax was an All Star, and received any MVP votes, was his seventh season in the Majors.

There's no comparison to make! Clayton Kershaw's peak was better, and it's not particularly close.

Clayton Kershaw's spread against the rest of his league was better than Koufax's spread against the rest of the league. Kershaw's ERA, ERA+, WHIP, and strikeout to walk ratio are all markedly better than Koufax's. Their FIP are virtually identical, which is mind boggling, considering that scoring was up during Kershaw's peak, and he pitched on a shorter mound, with a smaller strike zone. And he became an All Star caliber pitcher by his second season. It took Koufax until his seventh season to reach that level, and even then, his ERA 3.52 in 1961 was only about a half run better than league average (4.03).

And beyond all that, beyond each player's 6 year peaks, Clayton Kershaw has pitched at a high level. In 2017, which isn't included in Kershaw's 6 year peak, he led all of Major League Baseball with 18 wins. He led the NL with a 2.30 ERA, struck out 202 batters (against 30 walks), and he had a league best 179 ERA+. His K:BB ratio, 6.73:1, was the best in the National League.

That 179 ERA+ (which you say is flawed) is better than all but two of Koufax's best seasons, 1964 (186) and 1966 (190).

And last year? Clearly on the down side of Kershaw's career, now, he was still 8th in the Cy Young, going 16-5, with a 3.03 ERA (league ERA was 4.39, the highest in the National League since 2007), and 189 strikeouts in 178 innings.

Kershaw became a great pitcher much faster. His peak has been better, under tougher conditions for pitchers, and it has lasted far longer than Koufax's did. So, just stop this nonsense.

Kershaw over Koufax? Really? How about crunch time in the playoffs when it really counts? Kershaw is a joke compared to Koufax IMO Kershaw's Post season stats?? 9-11 with a whopping 4.63 ERA and that is with an always stacked Dodgers line up, any other questions? How many World Series wins??
