It’s the same answer you’re teachers gave you when you were in school. Study. I’ll add one more, get lucky. Yes, you need a little luck because footballs take funny bounces some times. Those bounces can go your way or can go against you. But there’s no getting around the study part. Anyone can look at a list of games and pick the team with a logo they like, or a favorite color. That’s where your luck better be good. If you’re a smart bettor, you will do your homework, study the lines, check the matchups, the trends, the home-field advantage and come up with your bet.
