			Kershaw has pitched more innings (2,454) in his career than Koufax (2,324) did.
 Kershaw (2,670) has more strikeouts than Koufax (2,396) did.
 
 Kershaw has a better K/9 than Koufax, 9.8 to 9.3.
 
 Koufax had 40 Shutouts, Kershaw has 15.  Kershaw is the active leader, as complete games are dead (unfortunately, personally).
 
 This old-school argument (which I don't think is generally invalid or necessarily bad, innings matter a lot I think, CG's not so much) doesn't seem to support Koufax over Kershaw.
