Premise: The 1921 NCAA football season had no clear-cut champion, with the "Official NCAA Division I Football Records Book" listing California Golden Bears, Cornell Big Red, Iowa Hawkeyes, Lafayette Leopards, Washington & Jefferson Presidents, and Vanderbilt Commodores as champions. Only California, Cornell, and Lafayette claim national championships for the 1921 season.
Hypothesis: The Lafayette Leopards claimed the national championships for the 1921 season.
