I know the conspiracy theories are cringe worthy but the amount of stupid, correctable ***** that I've seen over the years has jaded me.
The are parties within the NFL who absolutely try to rig the games and they'll fight to keep as much grey area in the rules and procedures as possible. Fool-proof measures (like tracking chips at each end of the ball) would provide way too much clarity. With the NFL embracing the gambling culture, this won't change anytime soon.
