I think rule changes like that would put the league at a risk of losing revenue. The big hits are part of why people watch. Take them away (or completely change the rules of football) and you run the risk of damaging the popularity of the sport. And if there's one thing the NFL isn't interested in, it's losing popularity (i.e., revenue).
