Kristaps Porzingis is expected to return to a Boston buzz saw Thursday at the Garden. Boston brutalized the Knicks, 110-89, in their lone meeting in late October at TD Garden. In the season’s third game, Porzingis shot 3-of-14 as the Knicks dropped to 0-3. Porzingis said he wasn’t getting any calls and some players complained nobody was correctly running Jeff Hornacek’s new offense. A lot has changed since, except the Celtics, who are off to a 26-7 start despite the traumatic season-opening leg injury to Gordon Hayward. Meanwhile, Porzingis is likely to make his return from a two-game absence with a sore left knee. He has never fared well against the Celtics, however. Boston’s brilliant coach, Brad Stevens, has always had an answer, even using guard Marcus Smart to pester the 7-foot-3 Latvian at times.
