Andre Iguodala defended the Golden State Warriors and stalwarts Stephen Curry, Klay Thompson and Draymond Green ahead of Game 2 of the NBA Finals, claiming their incredible careers should be appreciated "a lot more".

Iguodala, like Curry, Thompson and Green, is playing in his sixth Finals in eight years with the Warriors.

The veteran wing was the NBA Finals MVP in 2015, but his three team-mates have been the chief protagonists of a remarkable Golden State dynasty.

The previous five Finals have yielded three titles, yet the Warriors have work to do to add a fourth with this team after losing 120-108 in Game 1 at home to the Boston Celtics.

This is the first time the Warriors have lost Game 1 at home in the Finals, although the last team to suffer such a defeat were the 2013 Miami Heat, who recovered to win the championship.

Although these circumstances are new, there is little Curry, Thompson and Green have not yet achieved, and they were the subject of praise from Iguodala on Saturday.

"The overall sentiment for those three guys, after we won the first one, was that they were going to continue to be this dominant for this long," he said.

"I think we take it for granted because we're so close to our athletes now, we're so close to them on social media. We start to forget and take for granted.

"We should appreciate them a lot more. It's a really long run to go to the Finals, for this group, six out of eight years. It doesn't happen every day.

"Only the greats, real greats do it – LeBron's the only one around our era that's been able to have the same effect in terms of winning and getting this far.

"We've made it look normal, where people take it for granted and take certain shots at us. In previous generations, throughout sports in general, people understood how tough it really was."

Coach Steve Kerr is backing his key men to bounce back, even if the series opener was particularly painful as the Warriors threw the game away in a fourth quarter in which they were outscored 40-16.

Aided by a 17-0 run, that is the Celtics' biggest point differential in any single quarter of any road playoff game in their history.

"Draymond and Steph have been in the Finals six times now," Kerr said.

"They've seen it all, they've seen everything. They've won championships, they've lost championships. They've had their hearts broken, they've had parades.

"This is all part of it. That's the right mental approach, and it's one that is borne out of experience."

Meanwhile, Thompson suggested the early setback could benefit the Warriors after they "got comfortable".

"It was a harsh reminder but something we all needed to go through, including myself," he said. "It's about how we respond tomorrow, which I am very excited for."
