I played the UNDER tonight in the Southern Miss - Boise State game. I bet more on the UNDER in the first half more than than I did for the entire game as I believe both teams will try to establish a running game. If that does not work, then they will revert more to the pass. Considering both quarterback's skill level, I could see a pick-6, an interception for a touchdown, happening.
Also, we don't have to worry about Overtime with just a first-half UNDER. This is a strategy of mine I have used this year. With the reverting to the old time clock rule, we are seeing about 10 to 15 more plays in a game. Sometimes, especially more so in physically mismatched games, you will see lesser teams wear out allowing some easy fourth quarter scores.
24 is a very key number for betting on a total for a half. 21 is probably the second most popular number for half-time wagering. I don't like betting OVERS for the first half, almost only UNDERS.
Good luck tonight!
