Mavericks are hiding a serious defensive flaw that’s tearing them apart

It's no secret that the Dallas Mavericks were a flawed offensive team, but they struggled defensively, too. Dallas ranked 19th in defensive rating, 21st in opponents’ field goal percentage, and 23rd in points allowed. The root of those issues was clear. The Mavericks couldn’t defend the perimeter. Those breakdowns consistently forced their bigs into help situations, leaving the frontcourt to absorb the damage, and over time, wear down because of it.

The hidden cost of the Mavericks' perimeter breakdowns

Quantifying that strain isn’t easy — the eye test probably tells the story best. But NBA.com’s speed and distance data helps illustrate just how much Dallas’ frontcourt is overtaxed, and that's a direct result of constant perimeter breakdowns.

Bigs typically don’t cover much ground compared to guards or primary initiators. Yet Cooper Flagg and P.J. Washington led Dallas in distance traveled per game, both also ranking inside the league’s top 50. While their roles as forwards help explain some of that, the more telling number comes from center Daniel Gafford.

A drop defender and rim deterrent by design, Gafford still ranked sixth on the team in distance traveled and in the top half league-wide, an unusual workload for a player who should be anchored near the paint.

The real reason Dallas can't defend

But the strain on the Mavericks' frontcourt isn’t just about being literally overworked — issues in the backcourt are creating it. According to CraftedNBA’s CraftedDBPM, every Mavericks guard to log over 1,000 minutes (Brandon Williams, Klay Thompson, Max Christie, and Ryan Nembhard) ranked 208th or worse out of 268 qualified players.

None of these players is especially effective as a point-of-attack defender, nor do they consistently create defensive events. Among 227 players to appear in at least 50 games, Williams ranked 225th in isolation points per possession allowed, while Christie ranked 205th. Thompson and Nembhard graded out better in that metric, though both defended relatively few isolation possessions.

In pick-and-roll situations, the picture doesn't improve much either. Williams was relatively effective as a pick-and-roll defender, but the other three ranked in the bottom third of the league in points per possession allowed as ball screen defenders.

Looking at disruption, the issue becomes even clearer. No Maverick ranked in the top 100 in deflections or top 30 in steals, which is a sign of just how little pressure Dallas generates on the perimeter.

Even the team leaders, Flagg, Naji Marshall, and Washington, aren’t typically primary point-of-attack defenders (though a case can be made for Washington). Among the guards, Williams posted the highest steal and deflection numbers, but that production comes with a cost, as he consistently graded out as one of Dallas’ weakest defenders overall.

Dallas' paint defense is far from the only issue

Dallas’ rim protection only strengthens the case. The Mavericks ranked seventh in opponent field goal percentage at the rim, holding teams to 1.4 percent below their average within six feet. They also ranked 10th in the league in blocks, further underscoring the strength of their bigs.

The Mavericks’ porous defense was often overshadowed by their stagnant offense, but it remains a significant issue. Dallas has ample wing defenders and rim protection, yet must improve at the point of attack to field even an average defense.
