Golden State Warriors head coach Steve Kerr lauded an "incredible" Stephen Curry after his side progressed to a sixth NBA Finals appearance since 2015 on Thursday.

Curry claimed the first Western Conference Finals MVP award as the Dubs defeated the Dallas Mavericks 120-110 in Game 5, claiming a 4-1 series win.

The former unanimous MVP suffered an early injury scare, tweaking his right ankle in an attempt to trap Dorian Finney-Smith in the first quarter. After sitting out the early exchanges of the second quarter, Curry finished with 15 points on a relatively poor five-of-17 shooting for his standards, along with nine assists and two steals.

According to Kerr however, the 34-year-old's stamina and mere presence gets the Warriors going, while his effort on the defensive side of the ball deserves respect.

"He's our engine, offensively. Everything revolves around him," Kerr said after the win. "We've got a lot fo great players around him and guys who fit well together but it all starts with Steph.

"He just creates so much havoc for the defence that even on a night like tonight where he doesn't shoot the ball that well, he forces rotations and he frees up other players. His defence all year has been totally underrated.

"He's as strong as he's ever been. Conditioning-wise, just to play 35 minutes tonight, fighting over screen after screen after screen and then at the other end, be on the ball and get people open. Steph's incredible."

The Warriors moved to a 21-2 playoff series record under Kerr's tenure with the win over the Mavericks, after missing the playoffs in the previous two seasons.

After seeing through the long-term injuries to Curry and Klay Thompson over that two-year hiatus, Kerr believes his team started to find rhythm at the end of last term, ending with a 15-5 record over the final 20 games of the regular season.

"These last couple of years have been difficult with the injuries – worst record in the league two years ago," Kerr said post-game. "Last year it felt like we spent the year trying to get back on track and I think we did at the end of the season.

"It's pretty amazing. It's so difficult to get to the finals. An NBA season is such a marathon, to get through the 82 [regular-season games], then three rounds of the playoffs, beating the best teams in the league to get there, frankly, it's exhausting.

"For our team, our guys, especially the core group…to be part of that six times in eight years, I don't even know what to say. It just takes an enormous amount of skill and determination and work and I couldn't be prouder of our guys."
