Issues At Home?

And that's part of the problem

Do the Boston Celtics have a problem playing on their home floor?

When it comes to the playoffs, the answer is resounding yes.

How many times in recent memory have the Celtics headed back home, in control of a series, only to let go of the rope?

The numbers back this up.

If we look at all playoff games at home since Ime Udoka’s lone season with the franchise, we immediately start to get a clear picture. In 43 postseason home games, the Celtics have won 25, lost 18.

That’s a 58.1% win rate.

At first glance, you probably wouldn’t pin a team with such varied success on its home court as a genuine contender.

The thing is, that’s exactly what the Celtics have been throughout the entire stretch. Even this season, much to our surprise, they still rank among legitimate candidates to come out of the Eastern Conference.

If we broaden the search criteria to include every team in the league that has played over 20 postseason games on its home court from the 2022 playoffs to now, we get a shortlist of seven franchises.

Boston sits sixth.

Moments in time can skew these numbers. I mean, 11 of the Warriors’ 17 home wins came in 2022, when they last won a championship. Remove that run, and they’ve won six home games in 12 tries.

Boston has won a championship in that span, with its best home record in recent years, winning 9 of its 11 home games en route to the Larry O’Brien trophy.

Oklahoma did the same thing the following year, banking 11 of its 16 home wins over the past five years in a single run.

Let’s face it, all seven teams on this shortlist are there because they’ve been successful. That’s the point in filtering for a minimum of 20 postseason games on their respective home floors.

The problem is, even when factoring in championship runs, the Celtics still aren’t getting things done at home at the same rate as some of their contending counterparts.

The volume matters here, too. Boston's 43 games make it the most battle-tested number on this list. OKC’s .800 looks dominant, but it's built on 20 games. If they have a bad series or two, that number looks very different.

However, the Celtics have had enough chances, across enough series, that the sample is no longer small enough to explain away.

We’ve seen enough to know that this is who they’ve become as a team.

There’s something holding them back at home.

Interestingly, things aren’t the same on the road.

The Celtics have won 17 of their 24 road games since 2022, giving them a win rate of 70.8%. That’s a wild leap in productivity and success compared to playing on their home floor.

I’m sure we all have our own theories on what’s behind Boston’s issues with winning at home.

What I am going to say is that the current roster needs to be able to get things done with its own crowd behind it. Sure, this year’s Celtics are scrappier, younger and more athletic, but they don’t have the same depth of experience and a six-man rotation of borderline All-Stars to fall back on.

Role players are supposed to come alive on the home floor. Boston’s roster is so good this year because the role players have all developed their games and stepped into sizeable spots within the rotation.

You need that production.

Bluntly put, Boston had a wider margin of error in recent years. Now, they don’t.

If they keep dropping games at home, a trip to the NBA Finals will be nothing more than a fever dream.

Fortunately, the Celtics will be on the road when they look to close out their opening round series against the Philadelphia 76ers later today. That means, if we’re going by the numbers, there’s a 70% chance they wrap things up and book their spot in the Eastern Conference Semifinals.

Boston had the chance to close things out on Tuesday, taking a 3-1 lead back home. Now, the allure of shutting the Sixers down in Philadelphia will likely be enough motivation to get things done.

Assuming they take care of business tonight, the Celtics will need to look inward ahead of the second round, where the New York Knicks will likely meet them.

After all, in their past two playoff series — going back to the 2025 Eastern Conference Semifinals — the Celtics are 2-4 at home. Dropping these games can’t continue. Not when a championship is the ultimate end goal.

I’m all for the road dogs mentality, but only when it’s backed up by a fortress-style record at the TD Garden.

Home records are what you build a foundation on. Only then does the road record become a fearsome number.

For all of the schematic questions we might have about the Celtics, their inability to win at home has to be the primary fix. I’m just not sure how you get there, because it’s clearly not a coaching, talent, or system problem.

It’s something else.

The question is what?
