So far, the Philadelphia Eagles' toughest opponent could be themselves

A month into the NFL season, one team — Team A, let’s call it — has yet to gain more yards than any of its opponents.

A month into the NFL season, one team — Team A, let’s call it — has yet to gain more yards than any of its opponents.

Team A’s passing offense is ghastly. Last week, its rarely thrown-to star receiver posted a cryptic message on Twitter after the team failed to complete a single pass after halftime. Another MVP-level offensive weapon isn’t producing as expected, either. And statistically speaking, its defense ranks around average.

Those might sound like the hallmarks of a team going nowhere. But Team A isn’t the 0-4 Jets, Titans or Saints, or the stunningly 1-3 Ravens, either.

It’s the Philadelphia Eagles, who have followed a Super Bowl title last season with a 4-0 start to the new season. They join Buffalo as the lone undefeated teams remaining entering Week 5.

These are the same Eagles who have won 20 of their last 21 games and whose 12-game home winning streak is the second-longest in franchise history, since nearly World War II.
