Eddie LeBaron, at 5’7”, was the shortest NFL QB I ever saw. He was a good player for Washington, and then the expansion Dallas Cowboys. DLs were not quite so big in those days, but among the biggest was 6’6” 284# Eugene “Big Daddy” Lipscomb. One day, after being frustrated by chasing LeBaron around all afternoon, Big Daddy yelled at him, “when I catch you, I’m going to bite your head off and swallow it.” LeBaron replied, “If you do, you’ll have a lot more brains in your stomach then you ever had in your head!”
