The anti fun MIAMI RULES were a little balanced. Thill's personal rule about the six guns in the tunnel could be taken as aimed at offense. Other than those, most have been getting the game ready for girls to play.
Not sure if this is coming up in the context of spearing, but that's been against the rules since the 70s. I'd argue that rule changed benefited players on defense by deterring them from tackling in a way that could permanently put them in a wheelchair.
Nope. My least favorite was when defensive linemen could no long slap the **** out of the Olinemen's helmets. They used to try to take their heads off - and I think a couple times they had to call a timeout to clear the field of a loose head.
People now come to see the beauty of the game more than the violence. That has changed. It isn’t inherently bad. And staying the violence course would eventually get the game outlawed. It is on a good course. Violence in the controlled sense won’t be gone. Just more measured which is a civilized plan. Anywho.
