In a 48 minute game, 25 points made all the difference.

The Dallas Mavericks used an extensive first-quarter run to build an insurmountable lead, en route to a 133-103 victory over the Golden State Warriors Tuesday night. And in a game with tiebreaker implications, the Mavericks chose the perfect night to play great basketball.

Dallas brought it defensively against the Warriors. A typically sweet-shooting Warriors team couldn’t find the bottom of the net as they shot 21 percent from the field and had three made 3-pointers in the first half.

The rest of the game felt more of a formality than anything else. Golden State put together an effective start to the third quarter, but even that couldn’t register a dent in Dallas’ 30-point lead. For what felt like the first time all season, Dallas played harder than the team it played against for a full 48 minutes.

Dallas’ leading scorer on the game was Luka Doncic with 39 points on 15-23 from the field and 4-10 from three. He was aided by four other Mavs who recorded double-figures in the scoring department.

Leading the way for the ice-cold Warriors was Steph Curry who scored 27 points on 50 percent from the field and 55 percent from three.

Dallas finally got out to a fast start. What adds to the shock factor is that the Mavericks played extremely well on the back end of a back-to-back. That is something they haven’t done all season. And in a game with seeding implications on the table, Dallas played one of its finest games of the season; it was domination from start to finish. Let’s get into Tuesday night’s observations.

Key observations:

1.) Dallas played elite defense all night, and that led to its offensive boom. The Mavericks keyed in on Curry, who came into Tuesday’s game averaging 38 points per game in the month of April. In Three quarters of action, Curry scored 27 points, but Dallas took away “the others,” forcing Curry to beat the Mavs straight up. It wasn’t a fair fight. With the lack of offensive creators on the Warriors roster, Curry didn’t have reliable shot-making outside of himself all night.

2.) Dallas’ defense held the Warriors to 29 points, the lowest Golden State halftime score all season. Dallas put together a 28-0 run spanning from the end of the first quarter to the beginning of the second, marking one of the most potent runs of the season. To hold an offense that features Curry scoreless for that long of a stretch is elite team defense. Dallas needs to hang its hat on these types of defensive performances.

3.) Garbage time in the NBA is an interesting intersection of any game. Fans and coaches get extended looks for the end of bench guys. But what remains unknown is how valid the minutes played truly are. If a bench guy plays well against other bench guys, does it even matter? In tonight’s game, there was extended garbage time, and Rick Carlisle played everyone not named Kristaps Porzingis. How meaningful the minutes truly are will remain in question.

4.) Boban Marjanovic getting tossed from the game late in the fourth quarter was comedic. He looked as though he didn’t even know he was ejected. That won’t be a fun fine from the league office.

Looking ahead:

Dallas shocked everyone and made quick work of the Warriors. For a team troubled with inconsistencies, the Mavericks came out swinging. And with Tuesday night’s win, Dallas’ record improves to 34-27 on the season. And next up for Dallas is another contest against the Detroit Pistons. The last time the Mavericks played the Pistons, Dallas won 127-117. There are no easy wins in the NBA, but Detroit is a team Dallas should beat.
