Washington's offensive line entered the week rated the worst in the NFL. A day later, it lost Laremy Tunsil to a triceps injury. Now that line travels to Philadelphia, where the Eagles have built a defense that does not need to blitz to live in the backfield.
That is the matchup underneath the matchup. It is not about whether Washington's quarterback can make plays. It is about whether he gets time to make any play at all, behind a line that was shaky at full strength and now goes into one of the league's better pressure fronts down its best piece. Philadelphia does not have to dial up exotic looks to get home. Four rushers have been enough all year.
Washington sits favored to lose by 4.5. The number was set with Tunsil healthy. It is not anymore. The question is whether a line already stretched thin gets exposed enough to turn a manageable loss into something uglier, or whether Washington finds a way to protect what is left and keep this inside the number.
