John McEnroe was 14 when New York last won the NBA title.
Now 67, the former top-ranked tennis player and basketball fan is anxious to get back home from his TV commentating duties at the French Open in time to attend the Knicks' first home game of the NBA Finals.
"You can't ask for anything better. I've been waiting only 53 years," McEnroe said.
"So, time has come. It's going to be awesome because (Victor) Wembanyama is out of this world. Can't ask for a better match-up. It is like a dream match-up, it's like getting your best guys to do their thing."
The French Open ends on Sunday (Monday AEST). Game 3 of the NBA Finals is in New York the next day.
