Musso was the son of a coal miner who starred in high school sports in Collinsville, Illinois, and was therefore offered an athletic grant to attend James Millikin University. His father, who initially planned to pull him out of school after he completed his "primary" education, grudgingly allowed George to attend college.
College career
Musso attended Millikin University and was a standout in football, basketball, baseball, and track. Millikin was in the "Little 19" conference that included such teams as Eureka, Lombard, and Augustana. In 1929, Musso played against future President Ronald Reagan, who played guard for Eureka College and weighed about 175 pounds; Eureka lost to Musso and Millikin 45–6. Musso was already larger than most linemen of his era, playing college ball at 6' 2", 255 pounds. In 1933, Musso played in the East-West All-Star game, held in Chicago; it was there he first got the attention of George Halas.
Professional career
Halas, who had doubts the small school Musso could make it in the NFL, offered Musso a $90 a game contract (this was half rate for regular players at that time). Musso agreed and, although he struggled at first, became the centerpiece of the Bears line for 12 years. One reason the Bears of that era were called "Monsters of the Midway" was their imposing size—Musso, who played professionally at 270 pounds, was one of the largest Bears and one of the largest players in the league. His teammates called him "Moose." He played offensive tackle until 1937 when he moved to guard. He was the first to win All-NFL at two positions; tackle (1935), and guard (1937). He played middle guard or nose tackle on defense his entire career.
Musso retired to Edwardsville, Illinois, and began a restaurant business. He served as the Madison County, Illinois, sheriff and treasurer from the 1950s through the 1970s. He died in his home in Edwardsville in 2000.
