• Notre Dame: 1943, 1947, 1949, 1953, 1956, 1964, 1987
• Ohio State: 1944, 1950, 1955, 1974, 1975, 1995, 2006

What is the Heisman Trophy?

The Heisman Trophy is awarded annually to the most outstanding college football player and their school. The New York-based Downtown Athletic Club started the award in 1935. It was originally named the DAC Trophy until the death of player and coach John W. Heisman in 1936 when it was renamed the Heisman Trophy as a tribute to his “inventiveness and contribution to football strategy.”

“The Trophy remains a national symbol of collegiate football experience, prowess, and competitiveness, awarded annually to an athlete designated as the Outstanding College Football Player in the United States,” the Heisman Trophy Trust writes on its site.

The selection process is complicated – six individuals appoint state representatives, who select voters in the form of impartial sports journalists, former Heisman winners and one fan. Voters nominate three players on the ballot, and the player with the highest points wins:

• First choice: three points
• Second choice: two points
• Third choice: one point

Who won the Heisman Trophy 2022?

Southern California sophomore quarterback Caleb Williams won the 2022 Heisman Trophy, marking USC’s first trophy since 2004. 

Williams received 544 first-place votes and 2,031 total points. TCU senior quarterback Max Duggan was the runner-up with 1,420 points, followed by Ohio State junior quarterback C.J. Stroud with 539 points and Georgia senior quarterback Stetson Bennett with 349 points. 

Williams’ win brought USC up to par with Notre Dame, Oklahoma and Ohio State to add a four-way tie to the schools with the most Heisman trophies. 

But eight USC players have won the Heisman – the 2005 Heisman was vacated amid NCAA violations. Reggie Bush returned his Heisman Trophy after an investigation found that he and his family accepted cash, travel expenses and a home while he was a student. As of 2021, NCAA athletes can now profit from their name, image and likeness.

When is the Heisman Trophy awarded?

The 2023 Heisman winner will be telecast live on ESPN on Saturday at 8 p.m. from Jazz at Lincoln Center in New York City.
