He's pretty much the epitome of borderline HOFer. Of Baseball-Reference's 10 most comparable players, 5 of 10 are in cooperstown. I've always liked Mussina, but the closest he's gotten to the Cy Young was #2, once in 1999. I'm amazed at how healthy he had been in his career. They don't make 'em like Moose anymore. Without 300 wins or 3000 k's, I don't think he makes it.
