Brooklyn Nets head coach Steve Nash is happy with the continued progress of their 'big three' after Tuesday's 130-108 win over the Boston Celtics in Game 2 of their NBA playoffs first round series.

The Nets opened up a 2-0 lead with the comfortable victory, which comes after the 'big three' contributed 82 points in their 104-93 Game 1 win.

Kevin Durant starred with 26 points, eight rebounds, five assists and four blocks on Tuesday.

James Harden had 20 points, including four three-pointers along with five rebounds and seven assists, while Kyrie Irving added 15 points, six rebounds and six assists.

"It's about that time together on the floor, time together to understand, to gel, to make those connections that will afford us more down the line," Nash said post-game.

"It's the time and mindset we need to improve. I keep saying, we're not a team that's running this back three-four-five. We're trying to figure it out as we go.

"Each night is important, not only on the scoreboard but our development."

The Nets are 8-2 with the 'big three' in their line-up this season, but the contribution of Joe Harris, who had 22 points by half-time, to finish with 25 including seven three-pointers, cannot be underestimated.

"It's a nice luxury to have when he’s banging three balls like that and getting the crowd going," Nash said.

Boston lost star forward Jayson Tatum in the third quarter after copping a poke to the eye.

Celtics coach Brad Stevens said they needed to be much better all over the court.

"We've got to be way better. We've go to get down the floor quicker, we've got to execute faster, we have to be more detailed and better in our defense," he said.

"I was disappointed in how we played versus the other night."
