When you add up Tommy Heinsohn’s years as a player, coach and broadcaster, he began his 60th with the Celtics last night.

Maybe we should put that it capital letters, because 82-year-old Tommy Heinsohn is a CELTIC.

And he’s truly looking forward to this season, which hasn’t always been the case. For example, asked if he should have gotten more money for broadcasting the 15-win crew of 1996-97, he laughed.

“I can remember coming home and telling (late wife) Helen, ‘I’ve never seen anything like this.’ We were 0-for-February.”

Actually, the Celts were 1-13 that month (thank you, Toronto), but you get the point. And Tommy isn’t expecting such blues for the Green this season.

“It’s going to be fun,” he said before calling last night’s win against Brooklyn with CSN partner Mike Gorman. “I think they’re going to be really solid with the first unit. All the preseason games, every one of them, they showed really good chemistry. They all can pass. They can score.

“The key is going to be how they replace Evan Turner, and they’ve got people potentially who can do that, so they can play the same style for the 48 minutes. (Terry) Rozier and Marcus (Smart) and (Avery) Bradley and (Jae) Crowder, I mean, they can be devastating defensively. There were a couple of preseason games where they just shut people down, and everybody turned their back on them. They couldn’t handle the ball.

“So there’s some great stuff, great potential at both ends of the floor.”

But Heinsohn knows that, in addition to rookie Jaylen Brown, there are others who need to develop.

“Certain people have got to grow as players. I mean, we can’t just rely on Isaiah (Thomas),” he said. “He did a hell of a job last year, but other guys have to step up, too. (Al) Horford’s a big plus because of his experience. I look for Crowder to be a better player. I look for Bradley to step up a plateau.”

And while many, even Celtics players, are thinking their season will be judged on how far they can go in the playoffs, Heinsohn isn’t looking past the regular season.

“You never know (what’s) going to happen before the playoffs, injuries and what have you,” he said. “They’ve got the material to be good in the playoffs depending on who they’re going to be able to send out on the floor.

“Last year, we were competitive all season long, and when it ended up, we only had one guy who could score. Everybody was hurt.”

As long as the Celts can avoid such medical maladies, there is every reason to believe the club will be highly competitive in the Eastern Conference.

“It’s always fun when you’ve got a winning team,” he said. “But we didn’t always have a winning team, and to me, the fun of broadcasting is watching guys develop. . . . It’s great watching guys develop as players and people.”
