Knicks rookie Kristaps Porzingis appeared wise beyond his 19 years at the Las Vegas Summer League. For starters, Porzingis, who averaged 10.5 points and 1.8 blocks on nearly 50 percent shooting, had three swats guarding Jahlil Okafor, who is around 40 pounds heavier at 270, in a Knicks' win over the Sixers.Porzingis also demonstrated and early command of the Triangle offense, and showed a smiling and friendly approach with the tough New York media. Porzingis, whose nickname is "Zinger" in Europe, was such a crowd favorite that some fans screamed enthusiastically for him to shoot as soon as he caught the ball.
