Cowboys LT Tyron Smith vs. Redskins OLB Brian Orakpo: Smith has been making some of the league’s best pass rushers disappear. Clay Matthews, Julius Peppers, Jason Pierre-Paul — all non-factors the last month on his side of the line of scrimmage. Now he’s got Orakpo, who is coming to life for the Redskins with seven sacks in the past six games. He led the Redskins in tackles last week. He can be trouble against the pass and run, and it is up to Smith to contain him.
