Feeling good: The Dolphins' defense is tough up front, but they're not as tough in the secondary, and with Dez Bryant, Laurent Robinson and Jason Witten, the Cowboys and Tony Romo have enough downfield passing game targets to overmatch the Dolphins on the back end. They'll try to run it with DeMarco Murray, but even if that doesn't work and they find themselves having to outscore the Dolphins through the air, the Cowboys should be able to pull it off.
Cause for concern: The Dolphins' passing game has been better lately, with Matt Moore getting comfortable at quarterback and looking often for big, physical No. 1 wide receiver Brandon Marshall. With cornerback Mike Jenkins out and safety Gerald Sensabaugh a game-time decision due to injury, the Cowboys could have trouble finding ways to contain Marshall. If he's able to get open, he could beat the Cowboys with some big plays.
