Chiefs coach Andy Reid took over the team the same year Kelce was drafted in 2013, so he has watched his NFL career from the start. Over Kelce's 12 NFL seasons, Reid admitted not much has changed about the star tight end's work ethic. Even at age 35, he still has the same drive to compete.

The Chiefs might be influencing some fatigue as they look to become the first-ever three-peat Super Bowl champion. Travis Kelce is embracing any potential negativity, however, as Kansas City enters New Orleans to face the Eagles in Super Bowl LIX.

Jason Kelce made it clear previously that if he had to choose between rooting for his brother Travis in the Super Bowl or his former team, the Philadelphia Eagles, that the choice is the Eagles.
