Charles Barkley dunks all over pickleball: 'All these old people are killing themselves'

Former NBA legend Charles Barkley is certainly a very opinionated man, and when he has an opinion, he isn't afraid to let it fly.

The man who once famously said "I am not a role model" joined "The Kittle Cast" with NFL tight end George Kittle and his wife, Claire, and was giving out some rather sage advice about aging athletically.

For guys like Kittle and Barkley, going from the top of your game to retirement can be rough; it can feel like there's a hole in your life where your passion used to be.
