I feel for Buzzy in the case of Munson. Through 1979 he really was comparable to Fisk. Neither were Hall of Famers at that point.As a Sox fan, I liked Mattingly. He was a cooler. Then he quits and the Yanks go on a title run.
Then Munson died tragically while Fisk played another 13 years at a high level. It's unfair, but the HOF got it right.
But Buzzy's argument for Mattingly is full-on comical. In fact, the Yankees playing such a light-hitting first baseman was probably a big reason for their stinking up the league in the 80's and early 90's.
