Within minutes of winning Super Bowl LII, Philadelphia Eagles owner Jeffrey Lurie, head coach Doug Pederson and MVP quarterback Nick Foles were all quick to champion their fans as the best in the world. And judging by the images of the celebrations on Broad Street the night the city's beloved team captured its first Super Bowl title in the franchise's 57-year history, anyone can understand why. For decades, Philly football fans have expressed their deep devotion to their team in one-of-a-kind ways, complete with rousing choruses of iconic fight song, "Fly, Eagles, Fly" -a song that will likely take on new meaning in the years to come.
