One of the most useful betting tools on the Internet has to be the Breaking Odds Over Under Pace Calculator. This tool can be used for in game wagering or just to give you an idea if your pre-game wager is on pace to be a loser or a winner.
This tool can be used for football but it is primarily valuable in the sport of basketball. Obviously, basketball is a game of runs, so bet accordingly.
Also, it defaults to 48 minutes (NBA). If you are using it for college or international hoops, remember to adjust that field when you are setting the calculator up.
Note: There currently seems to be a problem with the code of the page. For the My Pick field that asks you to pick the side you took (over or under), just select Over. This field has no effect on the actual function of the calculator.
