Jalen Green had a phenomenal debut game for the Houston Rockets in the Las Vegas Summer League, but he is far from satisfied from what he showed.

The second overall pick of the 2021 NBA Draft balled out in his first outing for the Rockets, scoring a game-high 23 points on 9-of-18 shooting from the field. He shot 4-of-9 from deep and recorded five rebounds and two assists with just one turnover in 30 minutes of action.

While anyone would be happy with such performance, Green is not your average players. He knows the expectations on him are sky-high, and so he set the bar high on himself as well. The Rockets rookie said so as much after his debut.

“I feel like I can go higher than that level,” Green said on his Summer League start for the Rockets, per Alykhan Bijani of The Athletic.

The Rockets took down the Cleveland Cavaliers, 84-76, in their opener. Aside from Jalen Green, rookie Alperen Sengun also impressed with his 15-point, 15-rebound performance.

In comparison, Cavs big man Evan Mobley–the third overall pick of the 2021 draft–finished with 12 points, five rebounds and three blocks in the game.

On other contests, Detroit Pistons rookie Cade Cunningham had a poor outing in their 76-72 loss to the Oklahoma City Thunder. The top overall pick of the 2021 class made just 12 points on -of-17 shooting. He did fill the stat sheet with six rebounds, two assists, two steals and two blocks.

Fortunately for Green and the rest of his draft classmates, they will have more opportunities to show what they can do as the Summer League contintues.
