"I got a Nike outfit," said McVicker. "I'm going to wear it someday, on a special day."
Eric Brown, the director of recreation and healthy lifestyles at the Boys and Girls Club, says the basketball league they participate in isn't so much about competition, but rather skill building.
He says Antetokounmpo is someone the kids talk about a lot in the gym.
"I'm hoping it's life-changing for them," said Brown. "Just seeing that there's potential to get out and you are important enough for somebody as big as Giannis, a superstar, to come by and say 'I appreciate you.'"
Antetokounmpo says basketball helped him when he was young and he hopes it helps these kids as well.
"They've been supporting me since day one," he said. "Not just those kids, Milwaukee. As long as they had fun, I was having fun too."
