Jason Kidd didn't take kindly to his Milwaukee Bucks' 19-point loss to the Oklahoma City Thunder, after the latter put on a brilliant display in the first half, outscoring the Bucks 60-42.

Giannis Antetokounmpo shined in a 28-point night on 9-of-14 shooting from the field, but the rest of his teammates didn't fare as well, shooting a mere 42 percent from the field throughout the game.

Kidd didn't mince words when it came to his team's performance after a 4-2 start to the regular season.

“When you play grown ups you got to be ready and we weren't ready to play the grown ups tonight,” said Kidd, according to ESPN's Nick Friedell.

The Thunder's big three didn't register any shocking numbers, but their architect, Russell Westbrook, nearly bagged a triple-double through three quarters, sitting out the fourth after OKC had managed a sizable lead.

Antetokounmpo's rise to big-time prominence will help this Bucks team, but the rest of the team needs to be ready to follow and pick him up when he's not trotting out 30-plus-point performances.

The Bucks would be reduced to a mere 37 percent from the field without Antetokounmpo, a lack of efficiency that would prove the team's demise against one of the best teams in the West.
