NEW YORK — Kristaps Porzingis arrived in New York as a 20-year-old from Latvia, possessing the ability to speak four languages and having been trained for this moment from the time he was a middle- schooler. He played only 186 games for the Knicks before it came to a sudden end Thursday, but he saw things in that time that no amount of schooling could have prepared him to face.
