Also in the AL, and the East to boot. Kershaw is great, but benefits from pitching in a league without the DH, and a division with some great pitcher's parks. Phone Post 3.0

You can't be the best ever if you don't lead your team to a championship. Choking in the postseason doesn't help his cause. Phone Post 3.0

Career ERA+ which takes into account ballpark effects as well as league average ERA (steroid era)

1. Clayton Kershaw, 157 (1,690 IP)
2. Pedro Martinez, 154 (2,827 1/3)
3. Lefty Grove, 148 (3,940 2/3)
4. Walter Johnson, 147 (5,914 1/3)
5. Hoyt Wilhelm, 147 (2,254 1/3)

Pedro and Maddux were better Phone Post 3.0

Look at the innings pitched. The other players all had full careers, which means their numbers are affected by their eventual decline. The same will happen with Kershaw, and he will drop down the list. Phone Post 3.0

Absolutely ! We are witnessing history Phone Post 3.0

But, I think before we anoint Clayton Kershaw the best ever, he has to do it over his whole career.  Just a few years ago, Justin Verlander and Tim Lincium looked like they could be all time greats.   Walter Johnson has a ERA+ of 147 pitching almost 6000 innings.  Which is insane.

Ding ding. Randy, Maddux and Pedro all better Phone Post 3.0
Ill agree with that. He strings just a couple more seasons at his numbers he has to be in the convo at least Phone Post 3.0

Not yet, but it's definitely possible he ends up being #1 Phone Post 3.0

How is not possible? If Kershaw does this throughout the rest of his career, with albeit maybe a little decline, wouldn't that be enough? Phone Post 3.0

Kershaw is great and by far my favorite player. He is a future HOFer, but different eras. He also could use some more good playoff pitching. Cant wait to see what he does the rest of this year and the next few. Phone Post 3.0

You don't have to win a championship to be best ever, but he does need better playoff stats. Phone Post 3.0

Is his name Nolan Ryan?

Then no.

You don't have to win a title when you only play in 20% of the games. Agreed about the choking though.
