WALTHAM — Jeff Green  knew he was ready to come back when he was playing a pickup basketball game at his alma mater.
He told those in the game, “When I get the ball, I’m going to drive to the lane and I want you to hit me.”
Sure enough, they tested Green, making contact with his chest in the area of his heart where he had surgery last January to fix a faulty aortic valve.
“I wasn’t worried at all,” Green said. “When I got hit, I got hit right in the area where I had the surgery and it didn’t affect me at all. I think that is what got me through the rest of the summer as far as confidence and being able to build on what I’ve been trying to do. It was mind-boggling to go through it. First time, I was very winded but it felt very good to be back out there.”
Now for Green, it’s onto the business of getting back into the Celtics  system, something he thinks will come quickly.
“I don’t think it will take me long at all, with me being around the team last year,” Green said. “I’ve been here since beginning of September and I’ve had talks with Doc and assistant coaches just to figure out different schemes on the floor. Just to put it [to work] on the floor, maybe a day.”
As far as what the surgery experience taught him, Green said he has more perspective now.
“It made me appreciate the little things,” Green said. “When I had the surgery, I couldn’t move, couldn’t do a crunch, couldn’t turn left or right so it made me appreciate life itself and all the little things. Definitely helped me open my eyes and made me realize life is short and you have to enjoy every moment of it.”
Green and Chris Wilcox  both had surgeries on their hearts last season. “I call him my scar buddy,” Green said with his trademark wide smile.
