San Antonio Spurs coach Gregg Popovich left more questions than answers after Tuesday night’s preseason loss to the Miami Heat.

“We don’t have a starting lineup set in stone yet,” Popovich said before leaving the interview room. “It was a great game and we became more physical as the game went on.”

Popovich was very concerned about the Spurs’ turnovers, as they recorded 15 turnovers in the first half and another six in the second. With one preseason game still to play, it appears there is still a lot to be resolved before the start of the regular season.

“Miami is a great physical team, they come after you and we let it come to us,” Popovich said. “We let their physicality affect us. …We can’t have that. However, I thought we did a much better job in the second half.”

Jeremy Sochan led the Spurs with 18 points and 11 rebounds, almost single-handedly bringing his team back from a 10-point deficit, but it was Miami’s Bam Adebayo who led all scorers with 20 points.

“He did well, he was mobile, had a lot of energy,” Popovich said of Adebayo. “I thought he did well.”

Sochan said Miami was a very difficult opponent, but he thought the game went well other than the turnovers. He also said he enjoyed playing with Chris Paul, who led the Spurs with five assists.

“I think it’s natural, we know where we are and we play off each other,” Sochan said. “With an experienced team like Miami, we simply had too many turnovers. They are a good defensive team and made all the right passes.”

The Spurs will conclude their preseason on Thursday night on the road against the Houston Rockets.
