The genesis of this thread can be found in the thread "Great Doublers" in which I noted that Watson had scored in the NCAA long jump, shot and discus in both 1938 and 1939. I noted "before weightlifting and what that did to the throws."
Here's what Watson did in a list sense in those two years. Note that he could still make the U.S. lists in the long jump to this day, but that his shot marks are only high schoolish.
In 1938 he had marks of 24-11 3/4, 52-11 1/2 and 155-5. The discus mark made him only No. 37 on the world list for the year. The long jump had him at No. 8.... and the shot made him No. 3!
In 1939 he improved to 25-5 1/2 (led the world), 54-6 1/2 (No. 2 in the world) and 163-6 (No. 13 in the world). What a phenomenal talent.
Speaking of phenomenal talents, when Watson was No. 8 on the LJ's world list for 1938, the world leader jumped 25-6 1/2. That would have been one Jack Roosevelt Robinson, who set a World Junior Record with that jump.
You probably know him better as Jackie Robinson.
