I expect it to come down. I saw a poll on FoxSports.com where it was 50/50 as to who was going to win the game. If that many think Texas is going to win a lot more are going to take the points. As OU learned last year Colorado is not a good tune up for USC.
I feel USC can easily cover 2 TD's here if they want to, but on any given day, they could lose as well. In a best of 10, I'd wager USC to win a minimum of 8 in this match-up.
I hope they run the line to USC -10 or so. I am taking Longhorns on the money line.
Anytime a team makes this top ten, and is getting points at home or at a neutral sight, taking that team on the ML has been VERY profitable since the site was originated in 1997.
