If I could change one rule in hockey it would be suspensions. In my opinon, there is not enough being done in the NHL and hockey world to fight dirty, bad-for-the-game hits. malicious intentional head hits should not just get 5 or so games. it should be more like 12-16. When we make these serious life changing Hits more punishable, it discorages them even more. In my opinion, the current system is not doing that. We have to protect players. Protect the game. We need to get rid of these dirty career-ending plahys in our great game. I'm not saying get rid of all hits. im just saying get rid of the headshots, the  board head crunches, etc. These malicious plays have no place in hockey, at any level. I think the NHL's current spin the wheel system needs to change, and should of been changed years ago.
