The Dallas Cowboys have zero margin for error in their final four games. You can certainly argue that was the case before they played the Detroit Lions last Thursday, but that loss didn't mathematically eliminate them from playoff contention ... even if it did drop their playoff odds below 10 percent.
With a wild card looking like a pipe dream, the Cowboys will need the Philadelphia Eagles to continue their recent slide to catch them in the NFC East. What happens in their game against the Los Angeles Chargers on Monday night could very well decide Dallas' fate.
