Musial's most remarkable statistic is the one outside his control, 6.8% of those voting did not put him in the HoF at the first opportunity/first ballot. Sure, 93.2 is a sound first round showing, but who are the 6.8%?
The combination of adequate power (475 HRs), batting average (.331 career), and OBP (.417 career) coupled with the fact that he was brought into professional baseball as .. a pitcher ... indicates Mr. Musial had a unique knack for things like bats, balls, and gloves.
And yes, compared to his peer group, a sober decent chap.
