When Pihos returned to Indiana after his military service, he played at the fullback position for the 1945 Indiana Hoosiers football team that compiled the only undefeated record (9-0-1) in Indiana football history, won the program's first Big Ten Conference championship, and finished the season ranked No. 4 in the final AP Poll. He had only two days of practice before his first game back, Indiana's second game of the season, against Northwestern. He scored Indiana's only touchdown in the game, when he caught a pass at the Northwestern five-yard line and dragged three defenders with him over the goal-line. He scored the first two touchdowns in Indiana's 26-0 win over Purdue in the final game of the year. Pihos finished the season having carried the ball 92 times for 410 yards and seven touchdowns. He earned first-team All-America honors from Yank, the Army Weekly magazine, and finished eighth in voting for the Heisman Trophy.  As a senior, Pihos played three positions (fullback, halfback, and quarterback) and was named the most valuable player on the 1946 Indiana Hoosiers football team. In a show of versatility, and despite suffering from a throat infection and thigh injury during the 1946 season, he carried the ball 76 times for 262 rushing yards, completed seven of twelve passes for 84 passing yards, had ten catches for 213 receiving yards, and scored eight touchdowns. He ended his college career by scoring three touchdowns against the Purdue Boilermakers, helping the Hoosiers win the Old Oaken Bucket for that year. Pihos finished third in the voting for the Chicago Tribune Silver Football as the most valuable player in the Big Nine Conference.  In four seasons at Indiana, Pihos scored 138 points, which was then the school's all-time scoring record. He also broke Indiana career records for touchdowns and receptions. Bo McMillin, Indiana's head football coach since 1934, called Pihos "the greatest all-around football player our team has known in my time at Indiana."
