Bud Grant
Grant required outdoor practice during the winter to get players used to the cold weather[8] and did not allow heaters on the sidelines during games.[5] As per the latter practice it goes that Grant posited that with the heaters present on the sidelines the players would gather around the source of the warmth but if the heaters were not present the players would be paying attention to the game.

I think at least 3 of the 10 coldest games were Viking home games, but they’ve played indoors for decades now.
Back when it was a real man’s game.
That’s a great reference! More proof of my shallow knowledge of NFL coaches.
