Since taking over for Brad Childress in 2010, Leslie Frazier has won games in December of each season that have defined his tenure.
In 2010, he beat a good Eagles team on a dreary Tuesday night in Philadelphia in a game delayed two days by snow, signaling to owner Zygi Wilf that he knew how to inspire a team under the worst of circumstances.
In 2011, he coaxed the Vikings to the most franchise-damaging victory in recent history, as Adrian Peterson shredded his knee and winning kept the team from being able to draft Robert Griffin III.
Sunday at the Metrodome, on another snowy December day, Frazier earned his biggest victory as a head coach since he was running the upstart Trinity University program in the '80s and '90s.
"I am so very proud of our football team," he said.
The Vikings' 21-14 victory over Chicago means that the rest of December will matter, and that ...
• Adrian Peterson's pursuit of 2,000 yards could mean an MVP trophy for the best back in football. He rushed for 104 yards in the first quarter before settling for a measly 154. "Just keep handing it to him," said linebacker Chad Greenway. "He's unbelievable."
• This team has exceeded expectations. Few people outside the organization would have predicted more than six victories, or that this team would contend for the playoffs into mid-December. A 7-6 record and a victory over a division rival and playoff contender in December is a sign of growth for a team that was one of the worst in the NFL the previous two seasons.
