There was a lot that was strange or unfamiliar about the Eagles’ 34-29 victory over the Packers. In listing all the night’s oddities, you don’t even have to include the day of the week (Friday), the setting (Brazil), or the footing of the Corinthians Arena field (lousy, and comical if it hadn’t been so dangerous to the players). It was an unusual game in a few ways specific to the Eagles, and if these opening-night revelations turn into season-long trends, a team that already entered Week 1 with plenty of mystery around it will become even more intriguing.
