In the gambling world is know as booster week. What it means is boosters make up their money for giving to the school money. Each coach of the big spread schools (-21 or more) is committed to either cover the spread or not cover the spread depending on what the boosters of his school want in Vegas. So unless you know a high profile booster in these games don't bet them. Save your money for conference games. The season is still young. Don't blow your rolls on games decided by coaches and boosters.
