New Orleans Pelicans forward Zion Williamson is just 20 years old and only in his second year in the NBA, but he is already playing beyond his years. On Thursday, after the Pelicans’ 129-125 loss to the Milwaukee Bucks, Williamson showed that his maturity extends off the court as well.

When asked about a non-call on a drive he made in the fourth quarter against Bucks center Brook Lopez, Williamson said he needs to re-watch the play, even suggesting that Lopez may have had verticality in the play. The 2019 first overall pick added he’ll leave the officiating to the referees, according to Pelicans beat reporter Jim Eichenhofer.

Williamson’s drive with under two minutes left in the game resulted in a block by Lopez, but it looked as if he also caught his hand in the play. Nevertheless, the first-time All-Star’s refusal to say that the referees missed the call shows maturity, unlike other young players who will let the officials hear about it if they believe a crucial call was missed.

The high-flying Williamson finished the game with a team-high 34 points to go with eight rebounds, six assists, a steal, and a block. He made 15 of 26 shots from the field, but shot just five free throws, making four of them. He, however, also refused to complain about his lack of attempts from the charity stripe.

The loss to the Bucks was the Pelicans’ 18th of the season against 14 wins, and Zion Williamson and company will try to bounce back in their next game on Saturday against the San Antonio Spurs.
