Dodgers manager Don Mattingly addressed a number of topics in his season-ending media session Thursday. The big takeaway, as I explained in today’s editions: If the Dodgers didn’t beat themselves, and the manager only would’ve done one thing differently, then whoever assembled the team is primarily accountable for an early playoff exit.

That’s the manager’s opinion, and Don Mattingly doesn’t have the power to fire Ned Colletti.

But he did address Colletti’s status directly, and a few other things I wasn’t able to expand on in that piece:

• If his job is safe.

“I’m assuming. I came to work today like every other meeting. Nobody’s told me anything different, so I’m assuming.”

• GM Ned Colletti’s job status.

“I don’t know what’s been speculating but yesterday was an off day, we came in today and it seemed like business as usual. I don’t know what’s been said. I don’t do a lot of reading. … Would I be disappointed [if Colletti were fired]? I don’t know if it would — I would be surprised.”

• Will the entire coaching staff return?

“I’m proud of everything that we were able to accomplish this year.”

• The outfield situation.

“Early on, I’m trying to balance Dre and Carl, Matt, Yasiel, playing time, keeping everybody sharp. Finding out what’s our best team. So that was hard. I thought that would be easier and it wasn’t. It just got to a point where I knew I was going to make a decision on which way to go. Every once in a while on that, somebody would be banged up so it made it easier. But then when everybody got healthier I had to make the call on that. It really wasn’t four, it was five, because Scott (Van Slyke) was so good against left-handers.”

• Was Hanley Ramirez’s contract status a distraction for him?

“If you ask me my opinion — Hanley would really be the guy to answer it, and I can’t speak for him to say if he did or not — in my opinion I think it’s almost impossible not to. … That’s the problem when you get into your last year. Everybody’s asking the same questions.”

• On having enough prospects to replenish the National League’s second-oldest roster.

“We’re starting to hear more names, so that’s how you avoid that [aging]. It’s something we’re working towards. The whole, what ownership talked about when they came two years ago — they wanted to put a product that gives the fans a chance to win now. Do all the things at the same time and at the same time build the minor league system. You hear about it and it’s growing, like landscaping. It’s growing, it’s coming up, but you don’t see that part until it pops up. I think we’re getting closer to seeing more of it.”

• Have you talked to Josh Beckett about his retirement?

“Yeah, last night. I had a feeling that he was going that direction.”

• Is Dan Haren, who has a player option for next season, coming back?

“I haven’t heard anything to the contrary of that.”
