Yes i know another system I am working on about 4 or so right now. I was wondering if someone might have done this is one before and have back checked and know if it works. Here is the system it deals with offensive and defensive ratings. You take the offensive rating and subtract the defensive rating if you get a neg number then add to the other team. You do this for both teams and then you subtract the spread if you get a plus 5 then it is a bet. Has anyone done this?? thanks
