During his best season, 1961, he led the entire CFL with a whopping 1,794 yards, which made him known as the first running back in professional sports to rush for a mile in one season. He was an All West all star in 1960 and All Canadian in 1961. That year, Calgary finished with a mediocre 7-9 record, but defeated the Edmonton Eskimos in the Western conference semi-final. However, they lost the Western conference final to the eventual Grey Cup winner, the Bud Grant-led Winnipeg Blue Bombers. His best game was on September 3, 1962, in Calgary, when he scored 5 rushing touchdowns, still a Stampeder record.
In his career, he rushed 1199 times for 6994 yards, a 5.8 yard average, and 55 touchdowns, with his longest run being 85 yards. He is the Stampeder all-time rushing leader with 55 touchdowns and 28 100-yard games and is second among Stampeders for all-time rushing yards.
