And this game will certainly be well south of that number.
"It's going to be very cold," Kalina said. "There may even be a few flakes, but it shouldn't affect the game. Just really cold."
This isn't even close to the coldest game in NFL history, though. That distinction belongs to "The Ice Bowl" on Dec. 31, 1967, when the temperature at Lambeau Field reached minus-13 (with a minus-48 wind chill) in a contest between Green Bay and Dallas.
All week, Broncos players boasted about wearing short-sleeves despite the cool conditions. It was simply a matter of convincing the mind it really wasn't all the frigid.
"Once you get out there, you're on the field, you're just fine," Broncos receiver Demaryius Thomas said earlier this week. "But if you're just sitting around, that's when it gets to you. As long as you're out there on the field and warm, you're good."
The field should be in solid shape, though, with more than 20 miles of water-heated tubing under the field to keep it from freezing.
