SAN ANTONIO (AP) - The physical transformation was so dramatic one could be excused for wondering if the San Antonio Spurs had signed a new point guard in the offseason.

Gone was the somewhat doughy physique that jiggled when Patty Mills sprang from the Spurs‘ bench, madly waving towels to punctuate a basket by one of his teammates.

A healthier diet and improved conditioning has done more than transform Mills‘ physique. It has turned him from someone who led choreographed cheers from the bench to a key reserve that creates chaos on the floor with his long-range shooting and pestering defense.

“He’s a really committed player,” San Antonio coach Gregg Popovich said. “He came in this year with a changed body that he worked on all summer. Mentally he’s been making great decisions. He’s been a significant factor for us all season.”

Mills helped the Spurs earn the league’s best record, and the Australian native’s emergence could be even bigger now that Tony Parker is dealing with an ailing left hamstring.

When Parker left Game 5 against Portland in the second quarter, Mills responded with 18 points, three steals, three rebounds and two assists in 26 minutes as the Spurs rolled to a 104-82 victory to close the series.

“He is very aggressive,” teammate Boris Diaw said. “At the same time, he had to be a leader and he had to be under control like Tony does. He did it tonight.”

Parker sat out 14 games this season, including two weeks for what Popovich deemed “rest.” The Spurs were 11-3 without their All-Star point guard, and Mills‘ presence was a big reason behind that success. He averaged 10.2 points and 1.8 assists in a career-high 18.9 minutes per game.

“It was huge, it was huge,” Parker said of Mills‘ development. “Patty’s played great this year. He had a hard time the first couple of years to try to find a spot, but this year he came in and he was ready.”

Parker’s backups during his 13-year career have been a series of veterans on their last legs like Terry Porter or prospects who never quite worked out under Popovich’s system like Beno Udrih. His best backup, George Hill, was traded to the Indiana Pacers for the draft pick the Spurs used to select emerging star Kawhi Leonard.

Always direct, Popovich made no bones about what was keeping Mills from being a viable option in his previous two seasons with the Spurs.

“He was a little fat ass,” Popovich said. “He had too much junk in the trunk. His decision making wasn’t great, and he wasn’t in great shape. He changed his entire body. He came back svelte and cut and understood you have to make better decisions, point-guard type decisions. He did all those things better and he earned it. He’s been real important to us, obviously.”

While the 6-foot Mills is still listed at 185 pounds as he was last season, he is much more trim and toned. It’s earned him some playful teasing from teammates that he rarely wears a shirt around the locker room anymore.

“There is no way at all I would be able to play this long or strong for that amount of time last year,” Mills said. “I think my fitness base has given me the ability to play stronger for longer period of time. It’s definitely helped for sure, I’m glad I did it.”

After averaging 5.1 points in 11.3 minutes during San Antonio’s run to the NBA Finals last year, Mills quickly emerged as the team’s primary backup at point guard this season after entering the year behind Cory Joseph and Nando De Colo on the depth chart.
