Spurs players were up and at ’em Friday morning, many of them preparing to wander down to the lobby of the team’s hotel in Detroit suburbia to catch the bus to shootaround, when word began to filter out.

Shootaround had been called on account of weather.

Guard Danny Green used the unexpected snow day to accomplish two of his favorite activities.

“Ate and slept,” Green said. “There was nothing else to do.”

Had the Spurs known what was going to happen later at The Palace, that an offensively challenged Detroit Pistons team would hand them a 119-109 whipping, they might have opted to remain in hibernation.

Behind 26 points and 16 rebounds from Greg Monroe, 24 points from Brandon Knight and a season-high 21 points and five 3-pointers off the bench from Charlie Villanueva, the scuffling Pistons halted the NBA’s top winning streak at 11 games.

With a first-half 3-point barrage (7 of 11), Detroit raced out to a 21-point lead in the second quarter that had the ? Spurs (39-12) playing catch-up all night.

“They jumped on us,” said point guard Tony Parker, who had 31 points and eight assists with only one turnover. “We had a hard time to find our rhythm. After that, we were chasing the whole game.”
