The theory is simple... Risking 500 To win around +650 on a ML (which in all essence you're making an extra $150) try doing that 3-4 times in a row though with ML +130. I bet you it lands on 1 or 2 on the 3rd or 4th game. The extra +150 doesn't do you any justice if you lose your 500 risk. Remember that.
San Antonio Spurs At L.A. Lakers -1.5 I believe in the early 2000's ring a bell? I think vegas admitted they made the most on that game than any game ever in the history of sports wagering. All it takes is one time. But... that was just a bolt of lightning... apparently?
