When gambling on football you must look at the football gambling line statistics . Football game lines are set by casinos to try and split the action down the middle. Football point spreads are not used to predict how much a given team will win by. Casinos just care about splitting the action. For instance, if Carolina is favored by 3 over Atlanta. The casino just wants to even the action out. They may move the spread to 3.5 or 2.5 to get more bettors, and to make the action more even. If all the bets came in for Carolina and Carolina won, the casino would take a huge loss. Casinos are not into gambling they are into making money. Splitting the action down the middle ensures the casino will make money.
Football games normally end with one team winning by the following amounts: 1,3,4,6,7,10,11,13,14,17,20,21,23,24,27,28,and 31. I call these key points. When you see .5 added to a spread be careful because it could be a trap or a great deal. .5 can make all the difference in the world. If you get a spread of 5.5 then the .5 does not make a huge difference because most games don’t end with a team winning by 5. But a spread of 3.5 or 2.5 can make or break you. You must learn to read the gambling line statistics to determine why the casino placed the points where they did and why they moved a certain line.
Lastly when betting on football remember this, you are betting against the general public not the odds makers. The odds makers know everything the general public knows and they are trying to split the action based on the public’s knowledge. So the real question is “is the public wrong for this game?” For example the Colts lost Peyton Manning, now everyone is saying the Colts are going to get blown out. That is public perception, are they right or wrong? A couple of tips, normally when ESPN or any other sports guy is hyping a team, don’t listen. These guys just hype the team of the week. Also in the NFL the underdog wins a lot more than college.
