Dallas needs it more. Panthers have a chip on their shoulder so I'd say motivation won't be hard to come by for either team playing on the big stage.
Panthers defense has no holes outside of nickel corner. Their DL can get pressure without blitzing. LBs are going to make running difficult. I think it will actually be an ugly game.
Cowboys defense is actually better than they look. Easy to run on but hard to score on. Dallas actually has a TE cover specialist in Byron Jones but he probably won't be able to do it enough because our starter is out. Dallas is going to try and play keep away, have to protect the ball. Dez will get his if Norman is playing him 1-1. This is a big test for both teams but I don't even think Dallas is out if they lose because the Giants have some tough games. TOP is going to be big so whichever offense does the most with their opportunities wins. Hope its Dallas.
