Really! Some nertz on ESPN called him "one of the 5 greatest left handers" and I'm thinking - ARE YOU NUTS?? He was THE GREATEST lefty of all time BY FAR - 360 odd wins - well, here's baseball-reference.com's entry:

13 20-win seasons! 363 wins! He didn't play in his early years, because he was in the damn war!! 5200+ innings!! He basically carried the Braves to 2 world series. He did all this with brains, not brawn. He never bitched and moaned or took drugs. He was the best lefty ever. And he's almost unknown.
