Vegas will take all money and any money. The sooner the better. Of course a lot can and will happen, through out the course of the season.
I don’t know what LSU’s oddds were going into last season, but I’m sure Vegas made up for that by plenty of people betting on Alabama, Clemson, Oklahoma, Georgia, and Ohio St. Hell, I was ready to take a flyer on 100/1 odds on Utah last year when Moss, Anae, Fotu and Blackmon said they were returning. $100 bet brings home 10K. Not a bad risk/reward scenario.
This year, the risk of $100 is money gone with a completely new defense, QB, and RB.
