Jason Terry became a Celtic last summer with visions of deep playoff runs, and a chance to play for one of the game’s motivational greats in coach Doc Rivers.

Now that Rivers is expected to join the Clippers, though, could the party already be over? Terry has to wonder, now that the very different sound of rebuilding is starting to fill the halls on Causeway Street.

“I’m very surprised,” the 35-year-old guard said yesterday. “The reason I came to Boston was the opportunity to win another championship and to play for Doc Rivers. Kevin Garnett, Paul Pierce and Rajon Rondo were there. I wanted to be part of Celtics lore and tradition.”

And now? Good question, says Terry.

“Does that change things? I have to find out,” he said.

Terry has a lot to wait for, including a decision from president of basketball operations Danny Ainge on whether to keep Garnett or Pierce — or both — for another season.

“There’s a lot of summer left for us to adjust this roster to things,” said Terry. “Obviously you have the draft this week. Rajon Rondo is hurt, and he’s coming back from that. There’s just so much uncertainty that everyone is facing.

But Terry said he’s not going to ask for a way out. If rebuilding becomes the theme, and he isn’t traded, there’s a secondary purpose to his being here that started with last season’s chance to play for Rivers.

“From my perspective, I have to get healthy,” said Terry, who had minor knee surgery earlier this month. “I’m thinking about my future, too, and I want to be a coach. I learned a lot from Doc last year. Next season I’m still going to be under Danny (Ainge), and it will be an opportunity for me to learn his side of the business. This is still a great organization to be part of.”

Terry has been asked to help coach the C’s’ entry in the Orlando Summer League next month. Jay Larranaga, the only assistant who will still be under contract on July 1, will run the team.

“I’ll be helping a lot of things,” Terry said.
