If I could change one rule it would be having to go into the box after a fight. I think it would be really interesting to have players go right back to playing after something like that. Seeing who would go off the ice and who would stay on after that too. I think there would end up being more fights and possible a rule where everyone keeps playing as well. Being able to see how much more aggressive they are or if they end up fighting less to not mess up the game. Teams may move to enforcer type players and having players on each team to be ready for this. Having guys made to go out there just to fight and them come back out or star players not being afraid to fight. Fights also not creating disadvantage if your team is worse with 4 is cool as well. Seeing more 5 on 5 during the games as well.
