Golden State Warriors wing Klay Thompson emphasised that it all starts on the defensive end, while highlighting the performance of Andrew Wiggins after his side's 112-87 Game 1 blowout of the Dallas Mavericks.

The Warriors had seven players score in double-figures, led by Stephen Curry with a game-high 21 points and a game-high 12 rebounds, along with tying for the game-high with four assists.

While the Warriors' offense was strong, shooting 56.1 per cent from the field, it was their defense that won them the game, holding the Mavericks to 18 points in the first quarter and igniting a 15-4 run to start the third.

A main talking point from the series opener was the impressive performance of Andrew Wiggins, scoring 19 points while being the primary defender on Mavericks superstar Luka Doncic, holding him to 20 points on six-of-18 shooting with seven turnovers.

Speaking after the game, Thompson discussed the narrative that he is not the defender he once was and what he thinks makes the Warriors defense so good.

"I think our length, starting with Andrew [Wiggins] – he was moving them puppies tonight," he said.

"I still take pride in my defense, no matter what people say about if I've 'lost it' or not, I still think I'm a very good defender. Steph is in the [passing] lanes, obviously Draymond [Green], we can count on him every night on that side of the ball.

"I don't really pay attention to the noise [about criticism of his defense] – I know what I'm capable of, and I know what my team-mates are capable of. I knew we were able to do what we did tonight – it was just going to take a lot of focus and trusting each other.

"I'm trying. It's hard. Marking the best player every night for 40 minutes is not easy, and going to get buckets on the other end, but it's something I love to do. 

"All the best two-guards to ever play the game played both sides of the ball – whether it was Mike [Jordan], Kobe [Bryant], [Dwyane Wade], guys I really idolised as a kid – they all competed on that side, so I just try to follow the same mould."

Thompson went on to touch on the mediocre performance from Doncic, before showering Wiggins with further praise, saying he is happy people are finally seeing "who he really is".

"Luka is obviously one of the best players in the world," he said. "It didn't help that they played two days ago, off that emotional high of winning a Game 7, so we expect them to come back with a much better effort on Friday. 

"That's why [Wiggins] was the number one pick [of the 2014 NBA Draft]. You can't teach that athleticism, you can't teach that length or his timing. 

"I'm just happy the world is getting to see who he really is – an incredible wing player – and he will be like this for the next 10 years.

"I think him being here, he's allowed to be himself. We have so many great, talented players that it can be somebody's night and the ball will find them. 

"Andrew was incredible tonight, I can't say enough good things about him. 

"He makes my job so much easier, I don't have to check the best player every night – after what I've been through, that's a nice change of pace. He doesn't seem to get tired, his outside shot has greatly improved, and he's just coming into his own.

"It's just one game, and we can feel good now, but [the Mavericks] were down 2-0 and won their series last round."

Warriors coach Steve Kerr echoed Thompson's sentiments about Wiggins.

"I thought [Wiggins] was fantastic," he said. "Doncic is as difficult a cover as there is in this league, and we just asked Wiggs to try to hound him and guard him as best as he could. 

"He did a fantastic job – Wiggs is just a huge part of our defense and our team. I thought he was great offensively as well, so great night for Andrew."

When asked about the job the Warriors defense did on him, Doncic was respectful but had little to add.

"They did a great job – that's it, that's all I have to say. They did a great job," he said. 

"It's one game, that's what the playoffs is about. Whether you lose by one or you lose by 40, it's a loss, so we just have to get ready for Game 2 now."
