Since 1924, the NCAA has designated selectors whose teams are used to determine "consensus" and "unanimous" All-Americans.
Any player who is named to the first team by at least half the official selectors for a given season is recognized as being a consensus All-American.
The first player to do so was Red Grange, star halfback for the Illinois Fighting Illini, who received first-team honors from all six major selectors in 1924.
In 2020, Alabama tied a record set in 2003 by University of Oklahoma with five unanimous selections in one year.
Only 30 players have been selected a unanimous All-American in multiple seasons, the most recent being Marvin Harrison Jr. of Ohio State in 2022 and 2023.
