The New York Knicks got obliterated Tuesday in their season opener, done in by a deluge of Boston Celtics triples. An NBA record-tying 29 of them, to be exact. That taste was still in the Knicks’ mouths when they took the floor for their home opener Friday night, and the club used it as fuel to drill the Indiana Pacers 123-98 in Karl-Anthony Towns and Mikal Bridges’s home debut at Madison Square Garden. “Whenever you get your butt kicked on national TV in the NBA, it means you have to step it up,” said wing Josh Hart, one of four New York starters to finish with 20 or more points against Indiana. Bridges and Towns had 21 apiece, while floor general Jalen Brunson finished with a game-high 26. “I loved the way our guys responded,” Knicks coach Tom Thibodeau said. “The fight we showed was a lot greater.”
