Don't know if this is worth mentioning, but Stan Musial sent his son to Notre Dame during my time there. I believe that he was even on a football scholarship as a running back, but didn't play.
Also, Musial did his hitting heroics without a lot of support on the Cardinals. Red Schoendienst batted in front of him and was a great line drive hitter, and Enos Slaughter batted behind him and had some power, but there wasn't that much else in the 1950s. Also, pre-Roberto Clemente, Musial had probably the strongest throwing arm out of right field [when he wasn't playing first base].
There is controversy about Musial's actual role in Jackie Robinson's first year, but although Stan didn't like public displays of any kind, a lifelong St. Louis Cardinal follower/insider told one of my best friends that when all manner of ballplayer bigots were ramping up momentum for a ballplayers' strike, Musial told his teammates that he would not condone any such action and would take the field. Having the game's greatest player state that flatly, rapidly circulated through clubhouses and no strike occurred --- although Robinson got plenty of grief elsewise. Robinson, who was a bit of a harda$$, never appreciated Stan, as in his mind he wanted Stan to make larger public gestures welcoming him. Hank Aaron on the other hand always liked Stan Musial and they became friends. At All-Star games, the early black players wouldn't be welcomed by others and they would sit off alone. One Musial legend is that when he would see this, he'd go over to them, sit down, and say: deal me in, and they'd play cards together. Bob Gibson, another legendary harda$$, made an exception for Musial, feeling that Stan himself was a fine man, while grinding a bit at the rest of the Cardinals organization for not treating himself with similar respect [in his eyes].
Musial had relatively few baseball cards in his early career. That is because as TOPPS took over the field, they were engaging, in Stan's eyes, in some unethical business practices [I forget whether this had to do with the contracts or what]. Stan, the idealistic man, told them to take a hike for several years in the 1950s.
Musial took place in one of baseball's strangest plays, which also involved another of my favorites, Ernie Banks. With three balls and two strikes on the call, the Cubs pitcher through a pitch right past the catcher to the screen. Thinking it to be ball four [the umpire weirdly had made no call], Stan trotted down to first. The catcher thinking the same didn't bother to get the ball. A ballboy picked it up and gave it to a Cubs employee. The umpire, showing incredible incompetence, apparently shrugged [although he thought that it was strike three], and handed the catcher a new ball. On his way to first, Musial noticed that no one had gotten the ball and broke for second. The catcher was lobbing the "wrong" ball to the pitcher, who saw Musial heading for second, whirled and fired to a covering Ernie Banks. But the "real" ball had been handed to Cubs third baseman Alvin Dark, who also saw Musial running and also fired at Banks. Banks somehow understood which ball should be the real one [or just got lucky], let the pitcher's ball sail into centerfield, caught the one from Al Dark, and tagged Musial out. Stan sees the ball sail into center, gets up and runs to third. The Cubs outfielder retrieves the wrong ball, fires high and wide to third, and Musial "scores". Different umpires call Musial out at second and safe at home. After discussion, Stan, sadly is called out. Unsurprisingly the Cubs lost anyway.
