If you are not good at writing your own programs, I suggest you find a site that summarizes statistics you like to track, grab a schedule, and copy the stuff you like in the columns in the schedule.
For a simplistic example, the stats below indicate that the Panthers are 7-10 against the spread, while the Rams are 10-6.
This simplistic ATS trend would give the advice of making a strong play on the Rams. (Unless you think the line makers would over-react to this history so you go the other way.)
Formulas can get a lot more complicated than that, of course, so that is why I recommend starting with the stuff that is already on the web to help you get started and modify from there.

This particular site crunches available statistical numbers and comes out with a "Value Index"
But the figures that are generated by programs like this are usually purely technical, and don't take into account situational and emotional factors, recent injuries, etc, etc,. And, it would seem, playoff and late season games are particularly susceptable to non-technical factors.
I personally have had more luck with technical projections for mid to late season games in Pro Sports like NFL, NBA and NHL.
Simple, isn't it?
There's a lot more discussion like this in the tech room.
