Watch: Isaiah's son says 'fast shoes' key to stopping Wall

It's not easy to keep John Wall in check.

The Washington Wizards star was dominant in his team's first-round series against the Atlanta Hawks, and doesn't appear to be letting up in the East semifinals against the Boston Celtics.

Celtics point guard Isaiah Thomas asked his 5-year-old son Jaiden how to guard the fellow All-Star.

Isaiah: "He's really fast, so what do you gotta do to stop him?"

Jaiden: "Get fast shoes, and I will catch him. I will block his dunk."

Adorable.
