Didn't catch any of the first half, TP for a recap!

TP, but I got that much from the boxscore. Any explanation?
Celts struggled to hit shots early and the offense devolved into forcing up a lot of tough shots. Team recovered a little but the Spurs did a good job forcing weaker shooters like Crowder, Smart, and Sullinger to take shots and predictably the Celts laid a lot of bricks.
The Spurs had trouble hitting shots, too, but they have the size and talent inside to get to the line and force some shots in the paint, and that opened things up for their shooters.
