I don't want to see anyone get hurt but danger is part of the game.
Danger of paralysis or brain damage was "never" meant to be part of the game.
You can still get the monster highlight reel hits without slamming a dude in the head. That's what the rest of his body is there for.
You can also make a hell of a lot more hard tackles on a player without putting your head down and spearing him with your helmet. To quote scripture from the Book of Lombardi, Chapter 3, verse 10:
"And verily, God gave his Defender two arms and two shoulders, and bade him
'Go forth and wrap up the ballcarrier. Bear him to the sanctified ground in My name and await the whistle of angels before releasing him.'"
