Groza grew up in an athletic family in Martins Ferry, Ohio. He enrolled at Ohio State University on a scholarship in 1942, but after just one year in college, he enlisted in the U.S. Army and was sent to serve in World War II. Groza deployed as an army surgical technician in the Pacific theater, where he stayed until returning in 1946 to play for the Browns. Helped by Groza's kicking and play at offensive tackle, the Browns won the AAFC championship every year between 1946 and 1949, when the league disbanded and the Browns were absorbed by the more established NFL. Cleveland won the NFL championship in its first year in the league on a last-minute field goal by Groza. Groza set NFL records for field goals made in 1950, 1952 and 1953. "Sporting News" named him the league's Most Valuable Player in 1954, when the Browns won another championship. The team repeated as NFL champions in 1955.
