Mussina vs. Palmer: The debate continues
September, 29, 2008
At the end of a long and entertaining review ($) of an amazing Sunday, BP's Jay Jaffe takes me to task for arguing that Mike Mussina, as great as he's been, hasn't been as great as Jim Palmer:
Over the weekend, ESPN's Rob Neyer noted the supportive comments of former Orioles great Jim Palmer, who thinks Mussina is Hall-worthy. "I always said I thought he was every bit as good as I was," Palmer told the Baltimore Sun's Roch Kubatko. Neyer begged to differ: "He wasn't. Jim Palmer won three Cy Young Awards and finished with 268 wins and a 126 career ERA+. Mussina's got 269 wins, zero Cy Young Awards, and a 122 career ERA+."
With all due respect to Neyer, he's off base here. Mussina may lack Palmer's hardware, but over the course of his career he's been more valuable than Palmer was, and not by a little. Over the course of 19 seasons, Palmer pitched 3,948 innings and was 151 Pitching Runs Above Average and 1,064 Pitching Runs Above Replacement, worth 99.6 WARP3 according to Clay Davenport's system. Mussina, in 18 seasons totaling about 400 fewer innings, was 312 runs above average -- more than double Palmer, in other words -- and 1,302 Pitching Runs Above Replacement, good for 132.4 WARP3. Palmer's best seven seasons (his peak, in JAWS terms) were worth 64.3 WARP3; Mussina trumps that with 66.5 WARP3. Mussina's also got a considerable edge in career VORP (860.7 to 752.9) and a slight one in SNLVAR (99.7 to 96.2). Properly adjusted for the context of a more difficult work environment, he gains the advantage.
