It will light up around starting around 11am est. When the lines go up early in the week and their is a market(many sportsbooks with lines) some games get hit. Most CFB games are moved Friday night/Saturday morning or early afternoon.
You really have to play earlier in the week. Making bets today you really take the worst of it. Glad I got Maryland at 7.5, Duke at 1.5 and Rutgers as a dog.
