[3] He initially planned on attending the University of California upon graduation from high school in the spring of 1939,[7] but eventually decided upon Stanford, which offered him a four-year, full-ride athletic scholarship.

[3] Freshmen were ineligible for varsity play in 1939, Banducci's first year at Stanford, so he anchored the line on the school's freshman football team, earning All-Conference honors as a tackle.

[8] Banducci earned All-Conference plaudits during his 1941 junior and 1942 senior seasons at the tackle position, and was an honorable mention on some All-America lists.

In 1948, Banducci was part of a starting line that helped the 49ers set a new professional football record for rushing yardage in a single season.

[11] The newly-minted All-Pro guard and the money-losing San Francisco franchise[12] were unable to come to financial terms for 1955, however, and no contract was forthcoming — effectively ending Balducci's tenure with the club.

[8] Instead, Banducci explored other options, signing to play the 1955 season in the Canadian Football League (CFL) as a member of the Toronto Argonauts.

[14] Long in the tooth for the brutal game of football at age 35, Banducci additionally found the Toronto weather "too cold for a Californian like me" and retired after the 1955 season.

[3] After gaining his teaching certification, Banducci was hired by Marin Catholic High School in Kentfield, California as an algebra teacher and head football coach.

"[13] Teammate Vetrano acknowledged Banducci's superior stalling abilities and credited his skill for forcing an NFL rule change requiring teams to burn a time out for injury in the last two minutes of a game if trainers went onto the field to check out a player.
