Though QB records in sub-freezing temperatures tend to be classic examples of inductive reasoning, there is no debate that the zero degree temps are a bigger disadvantage for the Niners.

The oddsmakers are not accounting enough for how important Aaron Rodgers is to Green Bay. There are legitimate Super Bowl contenders and should not be home underdogs. If he were healthy all season, they would be getting a bye.

The Packers No. 1 goal entering the year was to develop a running game. Mission accomplished. Since Week 5, when Eddie Lacy returned from the concussion that kept him out of nearly two full games, he has rushed for 1,127 yards, the second-best total in the league behind only Philadelphia Eagles running back LeSean McCoy (1,139).

Aaron Rodgers and Randall Cobb returned to the field against the Bears in a big way, hooking up for two touchdowns, including the game-winning score on fourth down with 46 seconds left.

Cobb played 37 of the Packers 76 offensive snaps (48.7 percent) in that game, but made his only two targets of the game count. In fact, no quarterback and wide receiver combo has connected on a higher percentage of passes the last three seasons (min. 150 attempts).

Rodgers was 7-of-9 passing with 108 yards and a touchdown targeting Cobb against the 49ers in Week 1, including 3-of-4 for 74 yards when he targeted Cobb at least 15 yards downfield.

The 49ers secondary has allowed a touchdown on such throws in four straight games, after allowing a total of two in their first 12 games this season.
