Team president Don Smolenski, Swoop and dozens of green-clad Eagles fans and cheerleaders joined Nutter at the rally, at which he declared yesterday "NFC East Championship Fly Eagles Fly Day."
Standing next to a giant ice-sculpture trophy for the Eagles' division championship, the mayor led the crowd in the two cheers most familiar to the Linc: "E-A-G-L-E-S Eagles!" and "Boooo!"
"On. Jan. 4, 2014, the Eagles will start the new year with a face-off against the New Orleans Saints - Boooo! - for the postseason wild-card playoffs," he said, reading a city proclamation. "Now, Philadelphia's football fans can feel the unstoppable energy rising from the streets of South Philadelphia."
Many fans are hoping that today's frosty conditions - "real football in real weather," as Nutter put it - will help stymie Drew Brees and his high-scoring Saints, whose home field is under a dome.
Aside from improving the Birds' odds, there's another reason Nutter should be happy that today's playoff game is at home: It may give him some wiggle room in next year's budget.
The local economy is expected to realize a $10 million boost from spending related to the game, and the city's coffers could get $1.5 million in unanticipated tax revenue, according to estimates from the city Department of Revenue and the Philadelphia Sports Congress.
