Russell Westbrook and Paul George were teammates for nearly three months before Carmelo Anthony finally blessed the capital of Oklahoma as a destination worthy of waiving his no-trade clause. The mere opportunity to team up with Westbrook and George and form a potential Superteam, as they’re known in the modern N.B.A., wasn’t enough for immediate acceptance. Nor was the secret-weapon recruiting presence of the Thunder assistant general manager Troy Weaver, who had helped Anthony land at Syracuse University as a teenager. In an interview with The New York Times this week, during a break from preparations for his Thunder debut, Anthony revealed that he needed one more nudge before telling the Knicks last month that, yes, he was prepared to be traded to Oklahoma City. “My son said he wanted me to play for O.K.C.,” Anthony said. “Even before O.K.C. was in the picture.’’ Anthony proudly told that story on Tuesday afternoon after practice, lounging on a comfortable courtside bench while watching his son, Kiyan Carmelo Anthony, who is 10, work on his one-on-one moves against some Thunder staffers and, for a few minutes, Westbrook himself. On Thursday night here, Anthony will start at power forward for the Thunder and is likely to line up against the Knicks’ new face of the franchise — Kristaps Porzingis — in a nationally televised reunion. In the interview, Anthony insisted he held “no grudge’’ against the Knicks even after a 2016-17 season that he found so rocky and turmoil-ridden that it made it hard for him “to enjoy the game.’’ “You want it to work out so bad, for so many years, and it doesn’t work out — it’s not fun anymore,” Anthony said. He said the nagging sense that Phil Jackson, who was then the Knicks’ president, was “forcing me out,” gradually snuffed out his devotion to the franchise.
