I follow and understand most things about this great game, but I have never had explained to me why there are 8 inactives for every game. I can't think of a financial reason for it. The players go though the Training Camp and Pre-Season fighting to make a rosters spot. Then on game day, eight can't play. This has never made sense to me. I know it is the policy/rule of the NFL and has been so for years. But I'd like to get a definitve answer as to why they do this. Anyone?
