How Much Do You Bet?
How much is your bankroll for the coming football season? If you don't have a defined bankroll, you should. So let's ask it another way. How much would you be willing to lose betting football before you quit and call it a year?
2nd question: How much do you typically bet per game? I believe money management is one of the most common mistakes made by sports gamblers. Specifically, many bettors bet too much per game for the size of their bankroll. If you have more winning bets than losers, yet are down financially, then this applies to you. If you run out of money before the season ends, then it applies to you. If you think you are good at picking winners, but never seem to have winning seasons financially, then this applies to you.
3rd question: What is your historical win % in college football? IN the NFL? In other sports? If you don't have accurate records, start keeping them. Know your historical win percentage in each sport. Then use a basic Kelly strategy to size your bets...and they might be different for each sport based on your win %.
The link below provides a basic treatise on basic Kelly Strategy and a calculator to help you determine how to size your bets. Plug in different win rates...53%,54%, 55%, 56%, 57% etc. to see the effect on bet sizes assuming you have different win rates. Historic win rates is one way to calculate your win rate. Another is to plug in your actual advantage on any one specific bet to judge how much to bet on that one bet. There are links to articles explaining basic Kelly and calculating advantages. If you are currently a poor money manager with your gambling and don't have a structured approach to sizing your bets, then this might be the best advice you get all season.
