Prior to the start of any college football season, expectations for each of the 129 FBS teams can be expressed by a single number: That team's win total over/under. Over the summer, leading Las Vegas sportsbooks give each team a number, on which bettors can bet. If the number for a given team is, say, 7, and a fan thinks that team will win 8 games, the over is the play. If the team ends up at 8-4 or better, it's a winning bet. If the team wins 6 games or fewer, it's a losing one. If the team were to finish with 7 wins, equal to Vegas's number, the bet would be a push (no significant money lost or won).
