George Karl believes the Denver Nuggets did not have the right mentality to beat Golden State.

"When I talked about the playoffs, I told my team constantly: 'You don't understand how hard this is,' " Karl said. "I call it starting the fight. We started the fight in the second half of Game 3 against Golden State. ... Call it a young, cocky team. Blame it on an old coach who's too arrogant. Whatever. The lack of maturity of our team showed."

Karl is confident the Nuggets will make the necessary adjustments for next season.

"I think there's personnel development we need to do. And I think there's change in coaching. But we're aware of it, and I think we'll get it done," Karl said. "We're the No. 1 scoring team in the NBA. We're the worst-shooting team in basketball. We're one of the worst 3-point shooting teams in basketball. We're a team with a philosophy of getting fouled that didn't always shoot free throws well. And you don't think we're creative enough to figure out what we need or how to add to this team?"
