There may be no person outside of Cleveland who understands the specialness of the city more than Jeff Green.

The Celtics forward’s life and career was revived by heart surgery at the Cleveland Clinic roughly 14 months ago. He can’t think of a tribute more fitting than scoring the game-winning basket at the buzzer in the Celtics’ 93-92 victory over the Cavaliers last night.

The reason is the man Green spotted in the crowd as he bounded off the floor after his driving layup. Dr. Lars Svensson, Green’s surgeon, had a chance to watch his patient silence an entire building, save for himself.

“He said ‘Great game,’ and he’s proud of me,” said Green. “Just a year ago and a couple of months I was under that bright light, with him working on me. . . . It’s a blessing to be here. He’s paying attention to what I’m doing. That was for him, then. That was for Dr. Svensson.

“He did a terrific job to get me back to where I am now,” he said. “I owe a whole lot to him and the Cleveland Clinic. They welcomed me with open arms and I owe them for that. To have a game like this here, in front of my doctor, I think made him proud.

“I’m thankful, man, to have him and the way he performed the procedure. I’m lucky to be back on the court, and I owe it all to him. I’m just blessed and thankful.”
