Doc Rivers didn’t want to rebuild, so he left Boston for the Clippers. Now he’s watching summer league games and facing a reconstruction project in Los Angeles as the Celtics seek to clear the final hurdle with new faces. The Celts had hopes of making The Finals this past season, but injuries to Kyrie Irving and Gordon Hayward got in the way — though it still took a Game 7 stinker against Cleveland to knock them off the flight to the title series. Most teams have five-year plans, but rarely does one make it from tear-down to contendership in that frame. “That’s Danny (Ainge) and Brad (Stevens) and those guys — and, I mean, obviously the players, too,” Rivers told the Herald. “But they’ve done it as well as it’s ever been done, because all these other teams, including us now, everybody has a plan, but the plan has to work. And if it doesn’t work, then you have to start over again with another plan. And Danny and them have been able to run their plan.
