So to clear rollover at a few books I started doing this thing betting basketball both NBA and NCAA and wonder if it's actually a good idea or not. at one book I'll play any team that is -1 to -2.5 on the spread then bet the other team on the money line as long as the money line is +120 or better. I figure most of my bets will end in a push or a $10+ profit. I'm curious if anyone has data showing how often a favorite of 2.5 or less wins the game but does not cover the spread. thanks
