Video clips of the shot made the rounds on the Internet, showing Porzingis nailing the "hallway shot" while wearing flip-flops.
On Wednesday, the rookie explained that he needed just one attempt to make the shot.
"I made it on the first try and just walked away,” he said with a smile after the New York Knicks' shootaround at a club in San Francisco. "I had no doubt in my mind I was going to make it. It's a practice shot.”
Asked about the shot at the Golden State Warriors facility, Curry at first said he wasn't impressed with Porzingis' shot because the rookie's height makes it a bit less difficult. But when told that the 7-foot-3 Porzingis made it on his first attempt, Curry acknowledged that the shot was fairly impressive.
The Knicks will try to hand Golden State (60-6) its first home loss of the season Wednesday. The Warriors are 31-0 at Oracle Arena.
