"Through 1936, Caldwell was unbeaten from 174 pounds through heavyweight-and on one occasion, all three weights at one time. In a 1933 dual meet with UCLA, he weighed in at 174 but found his teammates at 191 and heavyweight were absent. He pinned the UCLA 174 pounder, won a decision at 191 and after a 10-minute struggle pinned the heavyweight, an all-Coast football tackle."
