The ranking is designed to identify the most significant outright underdog victories of each college football week using a consistent, data-based methodology.

CFB Vibes defines an upset as a game in which a team listed as the pregame betting underdog wins outright.

• The rankings use the final verified DraftKings point spread recorded before kickoff, as recorded by CFBD. The observation time and its age at kickoff are kept for every game and are available on request.
• A team that covers the point spread but loses does not qualify as an upset.
• Pick'em games and games without a verified pregame betting line are excluded, and counted in the coverage figures below, never guessed.
• Only games involving an FBS program are counted. The FBS side can be the favorite or the underdog.
• The larger the pregame underdog spread, the higher the outright victory ranks.
