James Harden tied a career-high with 61 points as the Houston Rockets beat the San Antonio Spurs 111-105.
"I don't know how you get any better. Whoever was in the gym tonight probably [saw] something they have never seen before. There's no way. That was one of the best performances -- the magnitude of the game, we needed it -- just everything," said D'Antoni.
Harden, who scored 57 points in his previous game, tied Michael Jordan and Kobe Bryant for most points over a two-game stretch.
Gerald Green agreed with D'Antoni's assessment.
"Some of the shots he hit today, it's remarkable. I've seen a lot of basketball in my life, played against a lot of people, and his talent level is just something that I've just never seen before...There's nobody that can stop him. He's just one of those types of players that he's able to get a shot off at any time. He doesn't have any weaknesses."
