VIDEO: Giannis Antetokounmpo's brother Kostas looks like Greek Freak 2.0

Milwaukee Bucks small forward Giannis Antetokounmpo defies everything a big man stands for. 

At 6-foot-11, the 20-year-old is a unique specimen with a rare combination of height, athleticism and tremendous ballhandling. 

Thanasis Antetokounmpo, one of Giannis's four brothers, has also gotten some attention playing for the NBA D-League's Westchester Knicks. But now, one of his younger brothers, Kostas Antetokounmpo, who's only 16, is quickly becoming one of the most intriguing prospects in the Midwest.
