There was a Daily News report that Porzingis voiced his frustrations to his teammates and Enes Kanter, another disgruntled Knicks veteran, confirmed those frustrations following Friday's 113-99 loss to the Celtics.
The 26-year-old center, who has also demanded a trade from the Knicks after having his playing time diminished, said that he spoke with Porzingis often -- including a summit at halftime during a game against the Thunder last month -- and added the 23-year-old was unhappy with how the team was treating Kanter.
"He was frustrated for me, too," said Kanter, who played 13 minutes on Friday. "He was frustrated at how I was getting treated. He actually wanted to go to lunch with me but the trade happened. He was so frustrated because I was so frustrated. He was texting me a lot to stay strong."
While Porzingis has spent this season rehabbing from ACL surgery he had last February, the losing culture was still bothering him, according to Kanter.
"Of course it will affect a player, for sure," he said. "But every time I was out there I want to win. I don't care where we are. You want to look at [a young player], send him to the G-League. This isn't the place to look. He was getting frustrated and he was seeing all the losses."
Kanter also does not understand the trade, which brought back Dennis Smith Jr., Wesley Matthews and DeAndre Jordan, along with two future first-round picks, because Jordan, 30, is older than him.
"I'm 26 and the guy just came is older than me," he said. "I don't know man. I think it's a little disrespectful. Only reason I'm not playing is they think I'm old. Now they bring in more old guys. I just feel a little disrespected."
