As the Golden State Warriors strive to make history, LeBron James believes the key to a successful season for the reigning champions is good health.

The Warriors tied the best start in NBA history with a win over the Denver Nuggets on Sunday, joining the 1948-49 Washington Capitols and the 1993-94 Houston Rockets as the only teams to start a season 15-0.

Golden State will aim to reach 16-0 on Tuesday to set the league record for most wins to start the season.

James was asked about the Warriors' exploits in 2015-16 and the Cleveland Cavaliers star said: "I think it comes with a lot of health. They've been healthy.

"They've been the most healthy team I've ever seen in NBA history, and they have great talent. Those guys all play for one common goal and that's to win, and that's all that matters."

James added: "They've just been consistent.

"I think the most impressive thing is the way they just they've been playing at a high level, man, for so long."
