One of the things that has been somewhat lost in the conversation this week, but could be a deciding factor is how sound the Cowboys and Packers are in the trenches.
Cowboys' offensive line vs. Packers' defensive line
In the past few years if you look at games where the Cowboys have struggled, a big reason for that has been the play up front by their offensive line. Due to some offseason changes and additions the Cowboys' offensive line led by RG Leonard Davis, LT Flozell Adams and RT Marc Colombo is one of the biggest in the NFL with an average weight of 328 pounds per player. This unit is big, physical and can wear opponents down.
