I was at the game ~ I usually get to one, in person, every 2-3 years. THE most surprising thing to me was the sheer number of Philadelphia Eagles fans that were there. I'm guessing that 10-15% of the fans in the stands were wearing Eagles gear. Based off of the official attendance of 77k that would mean there were 7,500-11,000 Eagles fans.
As we tailgated in the parking lot after the game waiting for traffic to thin down it was embarrassing that INSIDE LAMBEAU the Eagles fans were singing their fight songs enmass ~ very clearly audible outside (& I'm sure in the locker rooms).
Hardly a home-field advantage when Eagles fans are making noise during our offensive plays and the loud cheering every time the Eagles had a big play or scored.
