Jason Kelce delivered an emotional and enthusiastic speech via a video on X to Philadelphia Eagles players starting training at the NovaCare Center in Philadelphia.

The players reported July 23 and had their first practice game July 24, writes Anna Lazarus Caplan for People Magazine.  

Kelce shared his perspective on what it takes to succeed.

“Nothing in the world can take the place of persistence — talent will not,” the retired Eagles center, 36, told the team.

He described being a walk-on right out of high school, being told he was not good enough. Even after he was drafted “everyone said I was too small, I didn’t have what it takes.”

But the University of Cincinnati alum earned a starting spot on the Eagles and over 13 season became the greatest center to play the game.

“We are all so much better than you f—ing realize,” he told his former teammates this week. “The human mind is f—ing incredible Everyone here is here for a f—ing reason, I promise you.”

Kelce has been keeping busy in his retirement and will be starting as a broadcaster on ESPN’s Monday Night Countdown next season.
