The Greek Freak could soon be getting out-freaked by his own brother.

On Monday, Milwaukee Bucks star Giannis Antetokounmpo posted an Instagram photo of himself at a taping of WWE’s “Monday Night Raw” along with his family. In it, Antetokounmpo’s younger brother Kostas (second from the right) was looking positively huge.

Kostas, who is officially listed at 6-foot-10, currently plays as a forward for the University of Dayton and is still just 19 years old. He is averaging 5.1 points, 3.3 rebounds, and 1.5 blocks in only 16.8 minutes per game for the Flyers.
