Following Peyton Manning's February retirement that brought a close to his storied 18-year career, Gatorade honored him with a series of videos documenting some of the letters he wrote to close friends, family members, teammates, coaches and those whom he felt compelled to contact.

The stories are touching for different reasons, whether it's about the bond between brothers or a father and son, a friendship with a colleague who's battling cancer, staying in touch with the mother of a child who made an impact on his life, and expressing the appreciation for his time with coaches and teammates who made him the player he was.
