As the Spurs continue a homestand that started with a win over the Thunder Thursday night, a key cog of the rotation will be looking to build off the momentum of his 39-point performance.
LaMarcus Aldridge was having a slow start to the 2019-20 season until that breakout, which helped lift San Antonio to a 121-112 win over Oklahoma City.
"LaMarcus, obviously, was a beast," Popovich said after Thursday's game. "He was really good. He shot quickly, he made quick decisions and he also passed it out of there when he got doubled or there was a crowd."
Now Aldrige and the Spurs face one of their toughest tests of the young season: A 6-1 Boston squad that hasn't lost since their first game. But the Silver and Black have had the upper hand against the Celtics as of late; in their last 15 head-to-head matchups dating back to the 2011-12 campaign, Boston has won only once.
Tipoff is at 4 p.m. CT Saturday.
