I have the system. It was super the last 2 years. But this year hit a brick wall. Without getting to specific (because its basically dead and not worth playing), you look for teams that got swept and play them when they face the team that swept them. As soon as they win one game, your set. The problem this year is some teams have swept teams 6 or 7 in a row. So, its no good....
BTW, they also want you to buy the runs so you are +1.5 runs. So the juice gets f-ing crazy.
Anyways, forget buying that.
One last thing, Harvard stat boy is selling picks now from so called 5 systems he made. He doesnt release how they work just gives you the picks. They seem to be doing pretty well according to his feedback. I did not get them and I wont this year.
Hope this helps...PS, he has a NBA one that did quite well this past year and the last few years!
