The Ice Bowl was a game that should never have happened.
At the first blow of the refs whistle, it froze to his lips and ripped the skin off when he yanked it away. Apparently the blood just froze instantly. For the rest of the game the officials used voice signals.
A number of players were treated for frostnite, seven of a band were taken to hospital with hypothermia, and one spectator died from exposure.
I love watching the sport, but the NFL has never had much reasonable consideration to the health of those involved.
