Thanasis Antetokounmpo's NBA debut was a historic moment for the Milwaukee Bucks and the Antetokounmpo family. The youngest of the brothers checked in during the fourth quarter of the Bucks' dominant 123-99 win over the Dallas Mavericks, becoming the first active member of the family to play in the league. Thanasis finished with three points, sinking three free throws to officially get himself in the NBA box score. His MVP brother Giannis was watching from the sidelines, and microphones on the bench caught a visible reaction as the points went up. Thanasis admitted that the experience was surreal, having spent the majority of the season with the Wisconsin Herd, the team's G League affiliate. He noted that after attending countless games as a kid, putting on that jersey was a dream come true. Head coach Doc Rivers revealed that the superstar's nerves were through the roof before the substitution even happened. Thanasis signed a two-way deal back in October 2025, and his debut marked a significant moment for the family that grew up in Milwaukee.
