I need to give my input on a game I just watched.....

21 over? I am still waiting on your girl who ripped you off response.

You are covers NUMBER one BS artist

Here is MY interpretation of 1st half lines

You would think that the 1st half odds would be half of the full game odds. For some games, they are and for other games, they are not.

-For the games that ARE roughly half of the full game odds, the odds makers are basically saying either team can be leading. Hence half of the full game odds for the first half.

-For the games where the first half odds are greater than 50% of the full game odds, the odds makers are saying that the team should have a substantial lead in the first half. For example, a team like Alabama going up against a small school. Alabama will be -48 for the whole game. You would think that Alabama would be around -23, -24 for the first half right? Wrong. Usually a first half Alabama spread for a game like that is -29. If you're taking Alabama -29 for the 1st half, you're taking them at "-58 for the whole game" when they're only -48. This is to entice bettors into taking the first half dog spread of +29 points (which is usually a loser)..

In this scenario,  CMU "should have" covered that spread for the first half since you were paying a "premium." 

1st half spread of 7.5 x 2 = -15 for the whole game when they were originally -10.

You just got real unlucky with this scenario.

So, to sum it up from MY betting experience:

-if a team's 1st half spread is more than 50% of the full game spread, there's a good chance that they will cover the first half spread and blow them out.

-If it's less than 50%, I interpret it as the dog possibly leading in the first half.

-If it's half of the full game odds, it's basically a coin toss as to who will be leading at the half..

What channel is it on?
