Nobody celebrates losses, let alone ones in the dog days of March. But if you’re looking for signs about where this Celtics team is headed, this road trip provided plenty of those.

The Celtics beat Cleveland to kick off the road trip, but then fell to the top two teams in the West. They gave one away in San Antonio after Jaylen Brown’s ejection and fell two points short in Oklahoma City without Jayson Tatum and Derrick White. Nikola Vučević continues to recover from his right ring finger fracture, so he missed both games as well. 

In the standings, these are just two losses. Zoom out, though, and this was about as encouraging an 0–2 stretch as Boston could have produced. The road trip won’t satisfy anyone’s appetite for wins, but this time of year is more about figuring out what you actually have, and whether it will be enough when the games start to really matter.

If the point of this trip was to learn how Boston stacks up against the best of the West, the Celtics came away with plenty to like. They were short-handed, still integrating Tatum back into the mix versus San Antonio, and asking a lot of role players and young guys in high-leverage spots. Even so, they looked competitive, deep, and annoyingly resilient against two teams that could absolutely be playing in June.

The Celtics did not leave San Antonio and Oklahoma City with wins, but they did leave with evidence that this group might be sturdier and deeper than many of us thought — and capable of making elite teams uncomfortable even when the circumstances are far from ideal.

San Antonio tested the Celtics’ composure

The Spurs game could have unraveled in a dozen different ways, none of which would have involved Jaylen Brown being ejected.

Boston was already without Payton Pritchard and Vučević, then lost Brown in the second quarter on a double technical that everyone in green seemed to find absurd. Joe Mazzulla had his principal-versus-hall monitor line ready postgame. Derrick White called the second tech “bulls—.” Jayson Tatum made it clear he thought the officials were too eager to make themselves part of the show.

Once Brown got tossed, the Celtics had every excuse to fold. Instead, they kept playing like they have all season.

That might have been the most useful takeaway from the Spurs loss. Not that Brown got a rough whistle or that Victor Wembanyama is still a basketball glitch. Not even that White had a season-high 34 and Ron Harper Jr. dropped a career-high 22. It was that Boston got hit with a game-altering event against one of the hottest teams in the league and still made San Antonio work for everything.

Despite the early chaos, the Celtics were tied 58-58 at halftime. White then detonated for 19 points in the third quarter just to keep Boston within reach while Wembanyama kept answering everything with another three, another dunk, another reminder that he is somehow both enormous and fluid. Tatum, still on a minutes restriction and still feeling his way back into game shape, had a personal 7-0 run in the fourth that briefly made it feel like Boston might pull it off.

The loss exposed the margin for error against elite teams, sure, but it also showed how Boston tends to respond when things go sideways.

This group did not get shell-shocked or turn inward when they got thrown a curveball. They did not start playing like a team waiting for somebody else to save it. White kept cooking. Harper kept firing. Tatum kept competing. Mazzulla kept searching for answers, even if some of those answers involved getting weird with matchups and asking more from Garza, Walsh, and the rest of the rotation.

There was also something instructive in how Boston chose to defend Wembanyama. Mazzulla admitted afterward that, “against a player like that, you are constantly deciding what you can live with”. The Celtics clearly decided that if Wembanyama was going to beat them, they preferred him doing more damage away from the basket. That gamble burned them because he hit eight threes, but it wasn’t a crazy gamble. Sometimes a seven-foot-five alien buries your process anyway.

The bigger takeaway was that Boston stayed connected enough to make the game matter into the final minutes even after losing Brown and dealing with Wembanyama with his chaos dial turned up to eleven.

Yes, there was plenty of frustration afterward about the officiating and how the game unfolded. That was unavoidable, and arguably warranted. But underneath that frustration was something else: the Celtics sounded like a team that believed they had let a winnable game slip away.

That’s actually a pretty healthy sign.

Oklahoma City showed how real Boston’s depth might be

If the Spurs game felt like a bar fight, the Thunder game felt more like a high-speed chess match.

Boston went into Oklahoma City without Tatum, without White, and still without Vučević. The Thunder were also missing pieces, but they still had Shai Gilgeous-Alexander, Chet Holmgren, Lu Dort, and the best record in the league. 

The Celtics still came within one missed Payton Pritchard three of stealing the game entirely.

In fact, that might be the biggest reason this road trip felt so encouraging. The Thunder game turned into a showcase for all the players Boston will need when the games start to tighten up later in the spring. Brown was excellent, pouring in 34 points and seven assists while basically dragging the offense through long stretches. Pritchard looked like exactly the kind of bench guard every contender wishes it had, fearless and twitchy and apparently born to attempt impossible late-clock shots. Baylor Scheierman kept knocking down big threes. Hugo Gonzalez gave meaningful minutes, as did Jordan Walsh. Garza stretched the floor. Queta battled. Ron Harper Jr. kept doing Ron Harper Jr. things.

Payton Pritchard was asked what he’s learning about some of the young Celtics coming off the bench:

“We’re not learning anything. You guys have already seen it. They come ready to play and play winning basketball. So it’s nothing new.”

“It’s what they do.”

That’s a lot of useful contributions from a lot of different places.

For most of the season, Boston’s depth has been discussed as a nice story. Against Oklahoma City, the ‘young wolves’ looked more like a bunch of useful playoff assets. Not because Mazzulla is going to run 10 deep in a Finals game, but because the Celtics have a real collection of players who can hold up when a matchup or injury situation demands it. In last year’s playoffs, we saw just how severely injuries can change things in an instant.

Boston led 59-56 at halftime largely because the bench had 27 points and the ball was popping. They were up 83-80 after three, with the young guys continuing to make winning plays against one of the league’s most disciplined teams.

Oklahoma City is not the kind of team that accidentally lets role players feel good. The Thunder pressure every decision, make simple actions feel crowded, and turn “decent” into “a little rushed”. That slight rush is often enough to throw a wrench into any offense, but Boston handled it better than I expected.

Not perfectly, of course. The fourth quarter got sloppy and the turnovers were an issue all game. Shai got to his spots and looked, as always, like a man operating under different laws of physics. But the larger point remains: Boston looked like it belonged in that game, and it looked that way while missing two starters.

There is another layer to this, too. The Thunder seemed relieved to survive. Their fans were talking about a Finals preview, while their players and commenters were praising Boston’s shooting and toughness. That is usually a decent clue – great teams know when another great team has made them feel uncomfortable.

The Celtics did that.

And they did it while still very clearly having room to grow. Tatum, White, and Vučević were all out, meaning Brown had to do too much at times. Pritchard had to create more than usual. The rotation bent in ways that probably will not be necessary in a healthier, more settled playoff version of this team.

But Boston still nearly won anyway, and for a loss, that is about as useful as it gets.

Two losses, one pretty good reminder

Maybe the cleanest way to put it is this: the Celtics did not look overmatched against the Spurs or the Thunder.

San Antonio and Oklahoma City are two wildly different problems. One can throw Wembanyama at your entire offensive ecosystem and dare you to solve advanced geometry in real time. The other makes every possession feel sped up and slightly cruel.

Boston lost both games, but never looked out of place. In March, when you’re trying to figure out what kind of team you actually have before the playoffs arrive, that matters.

Because if these two games showed anything, it’s that the Celtics still look like a team nobody is going to enjoy having to beat four times out of seven.
