How could this be? Well, for one thing the Eagles have left far fewer runners stranded in scoring position.
Just kidding: Part of it is the level of competition. At 7-5-1, the Eagles have just the 8th best record of the 16 teams in the NFC -- that is, they're barely in the first division, although that will change if the Birds are able to win out. At 92-70, the Phillies had the second-best record in the National League, also with 16 teams. The fewer number of games in football tends to exaggerate win-loss percentages, and so does the existence of the Detroit Lions.
Still, our sports teams make us happy when they win and sad when they lose: By this measure we should feel happier about the Eagles than we did about the Phillies back in September, before we knew how the playoffs would turn out.
