A deflated LeBron James, dressed in a grey Miami Heat T-shirt and with a few beads of sweat on his forehead, was providing a postmortem of the shellacking the San Antonio Spurs had just given his team.

The Spurs executed one of the greatest team shooting performances in NBA history.

They humbled the Heat in Tuesday's game three of the finals, shooting an extraordinary 75.8 per cent from the floor in the first half, before cruising to a 111-92 victory and 2-1 lead in the best-of-seven game series.

As James dissected the loss, he turned his attention to the battle of the point guards.

"With Tony and Patty, those guys have very high motors, so we want them to match that effort," James said.

He was talking about the Spurs' point guards, France's Tony Parker and Australia's Patty Mills.

A year ago the Miami Heat defeated the Spurs in an epic seven game finals, but Mills wasn't a factor and his name wasn't mentioned by the world's best basketball player in any of the post game press conferences.

James has mentioned "Patty" in the last two press conferences.

At the start of the finals Spurs head coach Gregg Popovich singled out the Canberra-born 25-year-old, telling reporters his team wouldn't have had a chance at the NBA Championship if it wasn't for Mills.

"It's a bit strange actually," Mills laughed when AAP asked him about the praise.

"Pop doesn't have a lot of great things to say, but when he does you take it."

Plenty has been written about Mills' transformation from a towel-waving benchwarmer a year ago to his elevation this year to the Spurs' back up point guard role behind All-Star Parker.

Popovich used to call Mills "Fatty Patty", but when the Australian walked into the Spurs' training facility at the start of the 2013/14 season he was lean.

Mills says he only shed two kilograms in weight, but he altered his body fat percentage.

"My body fat percentage was 12 or 13 per cent," Mills said.

"When I came in at the beginning of the season I got it down to 5.8 per cent."

The remedy was simple.

"It was about me knowing nutrition," Mills, who cut dairy and bread out of his diet, said.

"I became more focused on what I put in my body, which I wasn't prior to that.

"Every meal is a conscious effort to stay disciplined and understand what's on your plate."

Not only will Mills and his Aussie Spurs team-mate Aron Baynes end up with NBA Championship rings on their fingers with another two wins in the finals, but Mills could find himself with a big payday.

Mills' two-year $US2.22 million ($A2.4 million) deal with the Spurs ends when the finals conclude.

The way the US media, James and even crabby old Popovich have been raving about Mills, he will likely end up with a fat, multi-year contract to go with his new, lean body.
