[1][2] Magliolo started school at Texas in 1939 and from 1940 to 1942 he came out for spring football practice, but it wasn't until the fall of 1942, when World War II created a shortage of players, that he tried out for the varsity.
Later in the season, when the Longhorns began playing against pass-oriented offenses in the Southwest Conference, William Harold "Spot" Collins became the starter because he was seen as the better pass defender and players went both ways at the time.
[8] That season, the Longhorns went 7–1–1, posted the school's first ever repeat conference championship, finished ranked #14 and tied Randolph Field in the 1944 Cotton Bowl.
[9] After leaving school to serve in the Navy for two years, where he was an executive officer on a PT boat in the Philippines during World War II, Magliolo returned to Texas in 1946.
[1] Magliolo spent much of the 1948 season on the sideline due to injuries, and, in July 1949, he informed the team that he was retiring from professional football to pursue a business career near Galveston, Texas.
In 1980, he purchased the Bay Area Racquet Club near the Johnson Space Center in Clear Lake, Texas and became an advocate for local tennis.
