Miami Heat forward LeBron James has criticised his team's accuracy when taking on three-point attempts as they fell to a 107-96 defeat in game one of their playoff final encounter with the Indiana Pacers.

James and Chris Bosh endured a frustrating evening at the Bankers Life Fieldhouse, with the pair having made just one three-pointer from 10 attempts on Sunday.

"I don't think we played a solid game all the way through. We made a lot of mistakes and they took advantage of it," James told reporters after the game.

"Obviously a three-point shot is a big thing for our team and tonight they weren't there. No-one had it going, we had some really good looks and they didn't fall and we've just got to do a better job executing in the next game.

"I mean they got some threes early on, our pick and roll coverage had a lot of breakdowns, including myself and I broke down a few times defensively."

The sides will meet again for game two on Tuesday in Indianapolis.
