It was a 'who's who' of the NFL at the Church of Jesus Christ of Latter Day Saints in Broomall, a measure of the respect the league has for Andy Reid.
Andy, his wife Tammy and their children greeted everyone personally.
The church was packed with more than 900 people, including members of the Eagles family, current and former players, coaches and management.
Team owner Jeffrey Lurie says it was a testament to how well Andy Reid is respected around the league.
"He's just incredibly respected around the National Football League, as you saw today by who came, by this team, the Eagles. Everyone who works with him just respects this man as a person," Lurie said.
Those in attendance also included quarterback Michael Vick, defensive coordinator Juan Castillo and former quarterback Ron Jaworski.
The NFL was well represented with Commissioner Roger Goodell, Patriots head coach Bill Belichick and Browns President Mike Holmgren.
Those who are close to the family say Andy and Garrett were more than father and son, they were best friends.
The league has rallied around the Reid family in the past when Garrett and his younger brother, Britt, were both arrested on drugs and weapons charges five years ago.
Garrett was found dead in his dorm room at Lehigh University Sunday morning. He had been working with the team as a conditioning coach.
Andy Reid has now acknowledged that Garrett lost an eight year battle with drug addiction, although the coroner has not yet officially released a cause of death.
Eagles players who'd been around Garrett daily say they thought he had overcome his addictions.
"Everybody had, he was great. He was in a happy spirits all the time, no indication at all," said punter Chas Henry.
Garrett lost his battle, but those who knew him say he left behind enough smiles to fill a stadium.
"Very funny guy. Everybody said the same thing today, we all knew the same Garrett. He was just a charismatic, funny guy and we're all going to definitely miss him," said defensive back Nnamdi Asomugha.
The Eagles continued their workouts at training camp without their head coach over the past two days. This was a scheduled day off but, instead of relaxing, they boarded buses to be here with the Reid family.
Former Eagles running back Brian Westbrook was among those who came to pay respects.
"It's a tough day. Unfortunately a young man lost his life and it's a tough time for the family, especially Coach Reid, really the whole family. I just wanted to be here and support them in any way that I could," Westbrook said.
Reid missed two days of practice, but plans to coach Thursday night's preseason opener against Pittsburgh.
"He wants to get right back in there," Lurie said.
