His book, Once A Cowboy, is probably the best Dallas Cowboy book that I have ever read. His humor was legendary, his toughness unquestioned, and his play was greatly underrated. He was a Cowboy in college (Oklahoma State), a Cowboy in pro football and a Cowboy in real life. Great story about his signing bonus when he signed with Dallas in 1966 - he asked for a horse trailer, and got it. Played with a broken collarbone in the 1970 playoffs, and as a fullback, showed a ton of grit despite not being particularly big (5'10", 210 pounds). RIP to a great character and football player.
