Walker's numbers are heavily aided by Coors field. 278/370/495 are his away career numbers. Very good numbers, absolutely...but should that stat line be in the hall? Mussina I can understand to some degree due to longevity and postseason success, but he was never really THAT good. He never won a Cy Young, finished in the top 5 a bunch but man the field was weak when he did. His best finish was 2nd in 1999 with a 3.5 ERA, he must have the worst ever stat line for a 2nd place CY young candidate. He also finished 5th with a 4.81 ERA in 1996. Mussina was simply a very good player for a long time, he was never an elite pitcher in the game. Schilling is probably more deserving than Mussina, but won't get in for off the diamond reasons. He had better career numbers and greater postseason success, including a world series MVP and the whole bloody sock thing. Schilling was very close to an elite pitcher, and definitely was exactly that during the postseason...when it mattered most. You greatly underrate how good of a pitcher Mussina was, and using ERA to do it, when he pitched during the highest run era ever, is a terrible way to judge a guy. He probably should've won the Cy Young in 2001, but he went 17-11, while his teammate, who gave up more runs, had a worse ERA+ and had less K's and more BB went 20-3, so he ran away with the Cy Young award. Nolan Ryan has a career ERA of 3.19. His ERA+ is 112. He was 12% better than league average over his career. Mike Mussina has an ERA of 3.68. His ERA+ is 123 for his career. 23% better than league average. He's every bit a deserving HOF, his 10 year stretch from 1991-2001 was incredible.
