There seems to be a new sibling rivalry budding up with Kostas Antetokounmpo being drafted by the Dallas Mavericks last month, and he isn't backing down. Kostas was drafted in the second round by the Mavericks and they see him as a bit of a project but the pressure is high on him because of what is brother Giannis Antetokounmpo has been able to do with the Milwaukee Bucks.

When the Bucks and the Mavericks face off there is one thing that isn't going to be happening, nice play because both of these guys want to shut the other down. Kostas said that he might let Giannis score once, but then he is going to lock him down. Via The Undefeated.

“I told [Giannis] I’m gonna try to bust his a–,” Antetokounmpo said, not even trying to hide his laugh. “I say that to all my brothers. We always say, if we play against each other, the only thing we’ll do is maybe let them score one time. Then after that, I’m locking him up.”

Kostas might have some trouble finding the court early in his career, and it wouldn't be surprising to see him make his way to the G-League to start the season. When the two guys do face off, it should make for some good entertainment with both guys trying to show that they are the better brother.

Right now Giannis has a big advantage but there is nothing stopping Kostas from being the next star in this league.
