The Dallas Mavericks have posted a top-10 offensive rating in each of the last 3 seasons. They have also posted a bottom-15 defensive rating in each of the last 3 seasons. This is why they have not won a championship.
The numbers (source: Basketball Reference):
- 2023-24: Offensive Rating 117.2 (7th), Defensive Rating 114.8 (18th)
- 2024-25: Offensive Rating 118.1 (5th), Defensive Rating 115.9 (22nd)
- 2025-26: Offensive Rating 119.4 (3rd), Defensive Rating 114.1 (16th)
Historical precedent: In the last 20 years, every NBA champion has finished with a top-10 defensive rating. Every single one. Source: Basketball Reference team rankings.
The 2011 Mavs? 7th in defensive rating. The Luka-era Mavs have never finished higher than 16th.
Where the defense breaks down:
- Perimeter defense: Opponents shoot 37.8% from three against Dallas, 8th-worst in the NBA. Source: NBA.com team opponent stats.
- Transition defense: Dallas allows 14.2 fast break points per game, 7th-worst. When they miss shots (and Luka's usage means more shot attempts from one player), the defense is caught in scramble mode.
- Rim protection: Without a true elite shot-blocker, opponents shoot 66.4% at the rim against Dallas per Cleaning the Glass. League average is 63.1%.
The structural problem: Luka's offensive workload makes him a limited defender. Kyrie has never been a plus defender. When your two best players are defensive liabilities, the other three starters have to be elite defenders — and Dallas has not constructed the roster that way.
The path to a championship-caliber defense:
- Add a 3-and-D wing who can guard the opposing team's best perimeter player
- Commit to a top-5 rim protector via trade or free agency
- Improve transition defense through schematic changes (designated safety role)

Every champion in 20 years has been top-10 in defense. That stat alone should tell the front office everything. Offense wins games, defense wins championships is a cliche because it is true.
