Best lefty off all time? My vote is Koufax!

"Yes, Koufax had less mental attributes. Koufax quit...which makes him soft. I would use another word, but don't want to offend anyone. If he isn't soft, then he is unreliable. Neither are good attributes. If he isn't unreliable, then he is made of glass. Again, not a good attribute in an athlete when there are others who don't have those issues."

So now you are a doctor. You could diagnose Koufax on his mental attributes and the extent of his rheumatoid arthritis. The stupidest statement yet that he is a quitter. You lost all credibility. Come to think of it, I would rather be a quitter than a cheater.

Yes me too. Thats why I agree with you in giving Randy Johnson two more Cy Young awards because, as you say "Clemens cheated" to win them over Johnson.

Seven Cy Young awards...pretty impressive. Thanks for pointing that out.

Back to original post - best lefty of all time. Longevity does count a lot toward "Best All Time", does it not? Peak value is also very important. And other pieces to the puzzle also count - stadium, mound, time in which they played, etc.

But if you are looking at the whole puzzle, chances are slim Koufax is the man. Grove and Randy Johnson are better choices - overall - all things considered.

Now if the original post was, "which lefty had the greatest Peak Value?" Koufax definitely then enters into discussion as possibly the best.
