Justise Winslow

Justise Winslow just lost Dwyane Wade. For his rookie season, the former Duke Blue Devil had a future Hall of Famer to learn from. Now, he's on his own.

Winslow is growing up fast. The 20-year-old is turning from mentee to mentor. Just look at him teaching the "Running Man Challenge" to 50 kids.

The video comes from the Justise Winslow Invitation Clinic, Winslow's first youth camp at his high school alma mater, St. John's School, in Houston.

Winslow previously went viral with the "Running Man Challenge" when he posted videos of him and his sister, Bianca, dancing after the Heat's first round Game 1 playoff victory over the Hornets in April.

Winslow's clinic was created in collaboration with the Robin's House Family Foundation, which was founded in 2016 by Winslow and his mother, Robin Davis. The foundation's goal is to "encourage and guide children and young adults to discover their highest potential through education, recreation, and community outreach."
