Koufax was great for 4 of his 12 seasons (the last four). Only six of his 12 seasons did he have a record above .500. Sub 3.00 ERA in only his last 5 seasons. There is not greatness in the whole of his career. I don't care how good he was for a few seasons, he doesn't belong in the conversation with many other pitchers, let alone Gibby and Marichal. Kershaw is considerably better than Koufax in a vastly different game. Jim Palmer was better. I could go on and could make a case that if Koufax is in the HOF (in my opinion his stats don't rise to that level), then Ron Guidry should be in (check the stats side by side). And, I've had this discussion with a former MLB pitcher (who is NOT nearly HOF worthy) and he agrees with my conclusion. 165 wins just doesn't make the cut for ANYBODY else...
