I've only met one successful bettor in my life. Every other one I've known was bragging one week, quiet the next, and bet games on TV. A loser.There are sports that if you are very savy and selective that you can profit on long term. NCAA college basketball has 365 division one teams that all play an average of 3 games a week. That's 500 lines that have to be posted weekly, no way can all 500 of those be sharp. No matter how smart the linesmaker, he has no way of knowing everything that's going on with Bellermine, Stephan F. Austin, Toledo etc. than he knows about the Packers.
This guy went to some school in Tennessee, and was obsessive about college sports in that area. Smaller schools, West Tennessee State Tech or some such ####. He would bore me talking about some player at some school I never heard of, who would never be a pro.
Some weeks he wouldn't bet, and some weeks he would have two bets. Never bet NFL games.
