What I enjoyed most about Mussina is how engaged he was in his post-game news conferences. When reporters ask stupid questions - and believe it or not, that happens on occasion - then most players are relieved and offer a rote answer. Mussina, however, was offended, and he could treat the questioner with disdain.
It was rude, on one level. But I always throught it reflected an interest of his to actually be insightful and honest, and the subsequent frustration he felt when the questions didn't meet his bar. Red Sox manager Terry Francona is the same way.
Now, for the bigger question: Hall of Fame? Probably. But I'm glad I'll have five years to think about it (assuming the BBWAA is still electing Hall of Famers in five years, which is hardly a sure thing).
