, a 27-yard field goal that would have given Minnesota a 12-10 lead with 22 seconds remaining.

Did the subzero temperatures play a factor?
Walsh said, "It's all the same. That field is what it is. We've done such a good job of mastering it all year on field goals. I picked a hell of a time to have one that I missed for the first time. The whole thing is on me, and I accept that. It's shameful. I have to do better."
Minnesota quarterback Teddy Bridgewater said "it really wasn't a factor at all. We were warm for the most part especially on the sidelines with the heated benches. You go out on the field. It's all a mental thing. It did not affect us at all."
"It was all good until my eyelashes froze," said Seahawks cornerback Richard Sherman, "then you kind of realize it might be kind of cold out here. I went out to warm up before everybody came out and took a jog. My contact lenses almost froze over. You can't ever prepare for that kind of weather or that kind of cold because it's like sitting in the freezer. "
Seahawks defensive end Michael Bennett said, "Usually when you go to games like that and the weather is like that, a lot of people are thinking about the weather. And for us not to be thinking about the weather and mostly winning the game. It says a lot about our team."
Coach has warm shout-out for the fans
Even with the loss, Vikings head coach Mike Zimmer applauded the Vikings faithful.
"I thought the fans were outstanding. They sat in the coldest game in Vikings history and were loud. I thought they did a great job."
Minnesota played their first outdoor home playoff game since the 1976 NFC Championship when they beat the Los Angeles Rams to advance to Super Bowl XI. Renowned Vikings coach Bud Grant, 88, was the honorary captain for Sunday's game and wasn't fazed by the big chill as he donned short sleeves for the coin toss.
The Vikings previous coldest game for temperature and wind chill occurred on December 3, 1972, against the Chicago Bears. The temperature was minus -2 degrees, with a wind chill of -19 degrees.
The coldest game of all-time was the classic "Ice Bowl" on December 31, 1967, between the Dallas Cowboys and Green Bay Packers for the NFL championship. It was -13 degrees with the wind chill of 48 at Lambeau Field in Green Bay, Wisconsin, that.
