It is the second time this season the show has visited the City of Brotherly Love.
The first was in October for the highly-anticipated face-off between the Temple Owls and Notre Dame Irish.
The show returned Saturday for the 116th Army-Navy Game.
"I've actually never been to College GameDay before. It's one of my favorite shows so I was pretty stoked to get the opportunity to come here and do that," said Cadet Lt. Zach Blankenbaker of the U.S. Military Academy.
For the past 13 years, Navy has been the victor.
"This is pretty much what we do. We always win," said plebe Fabiola Duran Juache with the U.S. Naval Academy.
But the cadets were not deterred.
"We have a shot every year. Any team can be beaten on any given day," said Cadet Cpl. Rachel Hornick with the U.S. Military Academy.
Legendary Navy quarterback Roger Staubach was the show's special guest as the hosts made their picks for the week but, for many fans and former military members, it was the high-ranking officers in the crowd that had them star struck.
"It's a little overwhelming. An admiral walks by and you have a moment of 'Oh!', but you realize you're not dressed in uniform so it's OK," said Jamie Bartlett of Louisville, Colorado.
Fans of both Army and Navy say while the rivalry is intense, there's a mutual respect that goes along with the military competition. And that's one of the best parts of the Army-Navy tradition.
"Being an American and seeing the camaraderie between the two teams is amazing," said Amanda Auckerman Flanagan of Columbus, Ohio.
"You'll see cadets and midshipmen jabbing at each other all day, but at the end of the day we'll be hugging and embracing and the fans as well. But it's electric. No other game matches quite what you have here," said Cadet Wyatt Frasier with the U.S. Military Academy.
