These are the 20 pitchers with the most wins, born 1949 to 1968. All stats through year 2000. The average of these "greats" was 3 hits better than their teammates. Roger Clemens gave up 9 less hits than his teammates gave up, per 800 balls in play (a full season's worth). I am not saying that these are the 20 best pitchers of that generation. But, this is a somewhat objective list.
