In my College Preview Magazine each year I devise many different formulas which look at teams that had good or bad fortune the previous year. The charts usually show those teams which had the good fortune generally do not have the same results the following season.
I call this method “Slipping and Sliding.” As I noted the last few years in the Turnovers=Turnaround article, results have been even stronger for the NFL than they have for college football. The reason is that there is far more parity in the NFL. In fact the difference between the best and worst team in the entire NFL is more narrow than the difference between the best and worst team within most college football conferences.
