When you turn on the television to see NFL games on snow-covered fields you know December football has arrived. With the playoffs around the corner, December stands for intensity and for many teams it means playing in inclement weather. The Bears outlasted the 49ers in heavy snow while the Packers got back on track with a win over the Texans in similar conditions. On Thursday Night Football, the Cowboys survived a close one in Minnesota to extend their win streak to 11 games. The Patriots and Raiders continued to fight for the top seed in the AFC with victories. The Seahawks eased all the 12's anxiety with a bounce back game at home against the Panthers on Sunday Night Football. Tampa Bay continued their win streak with a victory over the Chargers in San Diego. In case you did not know, the Lions are now 8-4 and sit in first in the NFC North.
