The weather is going to be cold, but of far more importance to this total going under is the health of each team's quarterback, method of attack and underrated defenses.




Aaron Rodgers' calf is getting all the attention. We know he won't be 100 percent. But Tony Romo also is playing hurt bothered by a bad back and rib injury. Neither quarterback will have any mobility.




Both teams are going to be run-heavy pounding away with DeMarco Murray and Eddie Lacy. Murray is wearing down having had the second-most touches in a season since 2006. He's lost his second gear. Murray is averaging only 3.3 yards per carry during his last 76 carries.




Both offensive lines are very good. But they are not that strong in pass blocking when their quarterbacks can't escape any type of pressure. The coaches know that so expect a lot of conservative play-calling.




The Packers have greatly improved their run defense. They can afford to play their safeties up in the box because of the coverage skills of their cornerbacks.




Cowboys defensive coordinator Rod Marinelli has done a masterful job of coaching up his defense. Dallas doesn't have much talent defensively. But its defensive unit has played with heart and cohesion. The Cowboys defense also isn't worn down because their offense has been able to control time of possession.
