BERMAX,
Just read this thread from top to bottom. Covers needs more stat/model greeks like you on this forum. From what I took from your opening post...you are completely unbiased and aren't familiar with the NBA. And IMO that is a good thing. If you eventually hammer down your system to get to a 55-60% succes rate you will be in plus money as long as you stick to your guns and don't let bias or "hunches" effect your wagers.
With that being said, here are a couple things that may help your system.
Turn over margin is important IMO. If team A has a -.5 t.o.m. and team B has a +2.5 t.o.m. that's theoretically 3 extra possessions for team B. Which is a possible 6 to 9 more points if team B were to score on those 3 extra possessions. From there you could calculate team B's shooting percentage/adj offense vs team A's adj defense and get a "ball park" # of the "probable" extra points off of turnovers for team B.
Another good stat to look at is SOS. How you would incorporate that into your system is up to you and if it fits into your system.
Personally, I always liked the theory that shooting% and offense is never guaranteed. A team can be off shooting the ball for many reasons, and visa versa(sometimes they just shoot really well) 2 things that are a constant are REBOUNDING and DEFENSE. I myself take into account rebounding always.
Good luck w/ your system.
**love the Boston/Charlotte #'s you posted. I locked into Boston +4 last night, and just hit the ML**
