he gets celebrated like he's a god, when in reality, his numbers were propped up by rules changes and performance enhancing drugs.He only played 12 seasons but its the final 6 that got him into the hall of fame. 6 SEASONS got him into the Hall of Fame...
let that sink in. So I'm going to break down the real reason for his successseason 7 - This was his breakout seasons, and his stats were basically on par for what would be considered an all star in todays era.
season 8 - Dodgers move into a pitcher friendly stadium and balls that would've left the park are routine fly balls which in turn drastically improved his ERA.
season 9 - This was the first year MLB expanded the strike zone. His numbers drastically improved all the way across. The correlation is obvious.
season 10 - He fukks his arm up. Doesn't play a full season.
season 11 - 12 Despite playing with arthritis he proceeds to throw over 300 + innings each season. he was shooting up all types of drugs just to pitch. Steroids are commonly used to treat arthritis.

So Koufax career changed when Dodgers moved into a pitcher friendly park, MLB expanded the strike zone and drugs/steroids.

. All while playing in a pitchers ball park and expanded strike zone. And check the ERA of the other starters during that run 



Lots of snubs in the baseball HoF, it's just as much about how much writers liked you as to how good you were as a player.
