koufax's arm was not trashed the last few years- but his elbow was.... his nastiest pitch was his curve ball, which he could not throw with a bum elbow.. they didn't have/use cortisone at the time - so as a major league hitter you 'knew' what was coming... it was his fastball- and they still could'nt hit it, knowing it was coming....

HOF worthy... in my opinion ...YES.... but as they say opinion's are like ....
