ENGLEWOOD, Colo. — New York Giants quarterback narrated a four-minute video on the legacy of his older brother, Peyton Manning, who will make his retirement official on Monday.

The video, which was written by Tom Rinaldi of ESPN, provides vintage photos from the Mannings as they grew up, through the development of Peyton Manning from the time he threw his first football in the backyard of the family home.

“It’s hard to described what he poured into the game all these years. His heart. His will. His mind. His body,” Eli Manning says in the touching video that was titled “Brother.”
