Peyton Manning's son does adorable pregame stretch with dad before Broncos game.

Championship cuteness.

Peyton Manning was joined by his 4-year old son Marshall on the field before the Broncos preseason game in Denver. Little Manning imitated his dad's every move, and it looks like there may be yet another quarterback in the family, just like his father and uncle.

The Broncos lost the game, but Marshall won everyone's heart.
