The Spurs were just one point ahead at half time in their 125-109 win, which gave them their 11th victory in a row.
The coach told reporters: "Probably the only thing I liked is that they hung in there. I thought we played really porous defense.
"I thought a lot of that was because LA was very aggressive. They were in attack mode, and I don't think we adjusted to it until maybe the end of the third quarter. From that point, I thought our defense was very good."
The Spurs sit top in the Western Conference, two wins clear of the Oklahoma City Thunder.
