I know the feeling about betting on a game and researching your stats but you still end up coming short. The main problem is that the Nba is full of lazy mofo's. Sometimes the players come out to play and sometimes they don't. This is usually the reason that the underdog might beat the favored team. Nba betting is more riskier in this sense. If you want to bet on basketball then stick to college basketball. You're more likely to lose more money betting the nba than any other sport.
