A system is only as good as the last year in which it worked. I know this system was good last year but I don't have any data for previous years. Does anyone have this info? Remember, a system or trend is often nothing more than a series of coincidences. I wouldn't blindly play a system without at least trying to analyze each particular matchup. A game may be favorable under one particular (historically successful) angle, but unfavorable under another (historically successful) angle. Isn't it at least possible that NC is favored because teams that win the national title one year tend to be overvalued in the following season?
