Ultimately just about every argument in favor of Sandy Koufax’s enshrinement in the Hall of Fame applies in almost equal force to Johan Santana. Both men were the best at their craft, leading their respective leagues in ERA, innings, wins, strikeouts, WHIP on multiple occasions and winning multiple Cy Young awards. Both were forced by injury to stop playing at too early an age.
If you can overlook the brevity of Koufax’s career because of his brilliance, then you might be able to do the same for Santana. Santana actually ranks ahead of Koufax in JAWS — which is Jay Jaffe’s Cooperstown Casebook system which averages total career WAR with WAR7. Koufax is 90th all-time, and Santana is 86th.
