1. The numbers are in. The Packers and Bears have made the playoffs in the same season in only four years of the rivalry's 89-year history. Next Sunday will mark the second postseason game between them; the Bears won a 33-14 Western Division playoff in 1941 at Wrigley Field. This season, the teams split the season series, with each team winning at its home stadium. Overall, the Bears own a 92-83-6 advantage in the series. One more number: According to ESPN Stats & Information, Packers quarterback Aaron Rodgers is 7-3 when the game-time temperature is 30 degrees or below. He has 25 touchdowns and five interceptions in those games.
2. The game will feature two quarterbacks coming off historic performances. As we suggested Saturday night, Aaron Rodgers played one of the better playoff games of this generation, completing 31 of 36 passes for 366 yards while accounting for four touchdowns in a 48-21 victory against the Atlanta Falcons. Rodgers' 86.1 completion percentage was the fifth-best in NFL postseason history, and he became the first quarterback to throw 10 touchdown passes in his first three playoff games. Meanwhile, the Bears' Jay Cutler also accounted for four touchdowns in a 35-24 victory against the Seattle Seahawks. According to the Elias Sports Bureau, Cutler became only the second quarterback in NFL history to both pass and run for multiple touchdowns in a playoff game. The other was Otto Graham, who did it in 1954 and 1955 for the Cleveland Browns.
3. Familiar, shamiliar. The Bears and Packers have been playing each other for nearly a century, but don't rule out a few schematic surprises. It will be especially interesting to watch the back-and-forth between a pair of notorious mad scientists, Bears offensive coordinator Mike Martz and Packers defensive coordinator Dom Capers. "With the coaches that are going against each other, coach Martz and coach Capers, there will be some new stuff out there," Bears center Olin Kreutz said. "So we'll be ready." Sunday, Martz provided a preview with three Wildcat plays -- including a pass from tailback Matt Forte -- and an early emphasis on targeting tight end Greg Olsen.
