Hey Rockne, you must be an old futz like me. I've seen in person everyone on your list, except for Willie Shoemaker. I only saw Musial play once, and it was near the very tail end of his career, so he wasn't the same player he was when he was younger.
You don't have Michael Jordan on your list. As a Bulls fan I got to see MJ in person about 7-10 times, and of course saw him play on TV probably 100 times. He was The Man.
I actually may have seen Willie Shoemaker, but didn't know it at the time. I'm not a horse racing guy. I've been to only 1 horse race in my life, but it was the 1973 Kentucky Derby, won by Secretariat. One of my college roomates was from Louisville, and he was really into horse racing, so a group of us went down to see the Derby that year. He kept telling us all this stuff about Secretariat, but it didn't mean anything to me at the time. We watched the race from the infield, where the college students and riffraff watched the race. The high society types watched from the grandstand. My two best memories of that day: One, Secretariat was a magnificent looking horse. Two, finding out that mint juleps pack a mean punch. My buddy's mom made a couple of thermoses of mint juleps for us, which we smuggled in with us. I drank a few too many of them.
Interesting sidebar on Secretariat. Some time after Secretariat died in 1989, Sports Illustrated ran a nice story on him. (Here it is for those interested:
https://www.si.com/longform/belmont/index.html) In the story they quote Dr. Thomas Swerczek, the vet who did the necropsy (an autopsy on an animal) on Secretariat after he died. Here is what he said:
“We were all shocked,” Swerczek said. “I’ve seen and done thousands of autopsies on horses, and nothing I’d ever seen compared to it. The heart of the average horse weighs about nine pounds. This was almost twice the average size, and a third larger than any equine heart I’d ever seen. And it wasn’t pathologically enlarged. All the chambers and the valves were normal. It was just larger. I think it told us why he was able to do what he did.”
In other words, because of his extraordinarily large heart, Secretariat was an oxygen making machine, which is why he kicked ass like he did.
