More important will be textbook TACKLING, since both Nelson and Cobb are in the top ten for receivers adding yards after the catch. Nelson in particular has a propensity for long TD RAC. I would say that Dallas handled Tate and Johnson pretty well. However, Nelson and Cobb are both pretty fluid, while presenting a more precise and tenacious threat to the Dallas secondary. The hope is that Rodgers is closer to 50% than 95% in the cold environment. We don't know if his tear is grade one or grade two, but having recently recovered from a hip flexor strain (grade one), it can take months before a muscle gets completely healed from injury. I spent copious amounts of time with ice and a heating pad. It is entirely possible that he could experience some tightening in such frigid conditions, where blood flow will naturally be reduced. Muscles don't really like cold temperatures, or the extremes between work and rest periods (if the Dallas running game owns the clock). This is why THE best defense for Dallas is a STRONG running game Sunday. They must own the time of possession and win the turnover battle...or else.
