From the beginning suggestion of Game 1, the Celtics sold out to take away the easy things from Dallas ' offensive harm. What changes are available to the Mavs?
These baskets that Luka Dončić and Kyrie Irving made in Game 1 of the 2024 NBA Finals? Brother, these are some cool baskets:
They are also, though, mostly tough baskets: difficult shots made over tight contests from one or multiple defenders, through contact, fading away from the basket, more likely not to clang clear than to fall through the net.
You know what kind of baskets are easier? Lobs to soaring 7-footers for extremely loud slam dunks, and drive-and-kick feeds to 3-point shooters waiting to cash out from the short corners. The Mavericks have been elite at creating those shots throughout the 2024 NBA postseason, with Dončić, Irving and the rest of Dallas’ playmakers (but, really, mostly Dončić and Irving) setting up 54 alley-oop dunks through the first three rounds, by far the most of any team in these playoffs, and generating corner 3-point tries on 13% of the Mavs’ shot attempts, the highest rate of any postseason participant.
Against Boston in Game 1, though? Just three total attempts from the corners — and one of those came in the final minute, with both teams’ stars off the court and the Celtics having long since salted away a blowout win — and only one look at a lob … which Jaylen Brown, in the midst of a stellar two-way performance, promptly snuffed out:

From the opening tip, the Celtics sold out to take away the easy stuff and force Dallas to subsist on hardtack. They pressed up tight on the Mavs’ corner shooters, at times even face-guarding them, even if it meant letting a dangerous creator like Dončić or Irving attack in isolation:
First: that his league-leading offense — particularly with the reintroduction of Porzingis — would be able to generate enough long-range looks that Boston would effectively be trading 2s for 3s, the kind of math problem the C’s have expertly posed to opponents throughout their dominant season. Nailed it. Boston took 48% of its shots from beyond the arc compared to 29% for Dallas, and went 16-of-42 from deep compared to 7-of-27 — a 27-point edge in one of the series’ biggest swing factors.
Second: that his No. 2-ranked defense would be able to consistently contain Dončić and Irving’s dribble penetration well enough, and force enough contested looks, that it wouldn’t get gashed by not sending additional help — and that, by inviting the Mavericks’ stars to attack one-on-one so often, even against perceived weak spots like Horford, Porziņģis, Hauser and Payton Pritchard, it’d bog down their whole attack.
Mazzulla nailed that one, too. The Mavs produced just 13 points on 24 possessions finished with an isolation, according to Synergy Sports — barely a half-point per trip and barely half of their elite regular-season mark. And by staying at home on shooters, almost never sending additional help on the ball — Boston switched on 14 of Dončić’s 38 pick-and-rolls in Game 1, according to Jared Dubin of Last Night in Basketball, and blitzed him only twice, according to ESPN’s Tim Bontemps — but showing plenty of help off it, the Celtics were able to completely dismantle Dallas’ ball movement.
The Mavericks made just 203 passes in Game 1, according to Second Spectrum tracking — 48 fewer than their average through three rounds, and 56 fewer than their regular-season average. They generated just 13 catch-and-shoot attempts — eight fewer than their average through three rounds, and nearly 12 fewer than their regular-season average. And, as you’ve probably heard, they produced just nine assists — by far a season low.
Force Dončić to take 26 shots to score his now customary 30 points, keep Irving from locating any kind of shot-making rhythm, force the likes of P.J. Washington and Derrick Jones Jr. to launch their 3-pointers from above the break rather than the short corners, and suddenly the mighty, flowing river of offensive production that washed away the Timberwolves starts to slow down to trickles and rivulets. The Mavs scored a microscopic 75.3 points per 100 possessions in the half-court in Game 1, according to Cleaning the Glass — their worst half-court scoring game of the 2024 playoffs and fourth-worst of the season overall, a whopping 27.8 points-per-100 below their regular-season average and 32.5 points-per-100 fewer than they managed against Minnesota.
At the risk of going out on a limb: I don’t think Your Worst Scoring Games of the Season are going to be enough against this Celtics team. To have a shot at taking four of the next six, Dallas has to find some offensive answers, and quick.
The path starts, to some degree, on the defensive end. The game is connected, as Mazzulla is fond of saying; the difficult job of beating this Celtics defense becomes much harder when you’re taking the ball out of the basket over and over again. The Mavericks’ only real run in Game 1 came early in the third quarter, when the combination of their defensive effort and some less-than-locked-in Boston offense resulted in a string of empty Celtics possessions. Get some stops, and you can inject some more pace into the game, find some opportunities to run a little more early action before Boston’s defense is set, and manipulate the chessboard more to your liking to generate better scoring chances:

Some double-drag screens in transition, or staggered screens high on the floor, could get multiple Celtic defenders moving — and, more importantly, force one of Boston’s bigs onto Dončić or Irving’s preferred screeners, lifted away from the basket. Dealing with the way Boston’s wings and guards shrink the floor and swarm to protect the rim still isn’t exactly a picnic. But navigating a packed lane is a little bit easier, at least, without a 7-footer in the mix.
Dallas tried to open things up by having Lively screen to get Tatum to switch and then bringing Porzingis in the action. Luka was able to split here and you see the help that came on the drive. pic.twitter.com/HngKUBSuTp

Jason Kidd’s chief task heading into Game 2: getting Irving untracked. More pace would help here, too; if Irving’s consistently sprinting into catches and making a beeline for a basket, as he did in Game 1 against Minnesota last round, it makes the project of defending the Mavericks much tougher. Maybe Kidd dials up some higher ball screens, up near half-court, to give Irving a runway to the rim; maybe, if he gets a couple of finishes to go early, he can lock into the rhythm that eluded him Thursday.
And at the risk of being Captain Obvious, maybe most important of all: Dallas’ shotmaking has to be much, much better than it was in Game 1.
When the Mavericks actually can create a clean look against this Boston defense, they’ve got to take advantage. Because if the Celtics stay as locked in on that end as they were in Game 1, they might not get too many more.
