Giannis Antetokounmpo's Brother Kostas Declares for NBA Draft

Kostas Antetokounmpo, the brother of Milwaukee Bucks star Giannis, is going to throw his name in the 2018 NBA draft class, per a Twitter announcement from the younger Antetokounmpo: 

ESPN.com's Jonathan Givony was first to report the Dayton freshman will declare for this year's draft and that he could opt out if he doesn't get positive feedback from NBA teams. 

Antetokounmpo was forced to sit out the 2016-17 season due to an NCAA ruling that deemed him a partial qualifier since he attended high school in Greece for two years before his family moved to Wisconsin. 

As a redshirt freshman last season, Antetokounmpo averaged 5.2 points and 2.9 rebounds in 15.1 minutes per game. The 6'10" power forward is not ranked among the top 50 draft prospects this year, per B/R's Jonathan Wasserman. 

Givony also noted Antetokounmpo won't seek a transfer from Dayton, making it possible he returns to the school next season if he withdraws from the draft. 

The Antetokounmpo family has turned into a basketball powerhouse. Giannis is a two-time All-Star who has developed into one of the NBA's best all-around players. Thanasis was a second-round pick by the New York Knicks in 2014 and is playing for Panathinaikos of the Euroleague.
