Spurs were just running basic sets again last night and yes, the intensity was pretty low last night.
Spurs weren't getting the #1 seed. But I do believe Pop will go for the 41-0 record. Pop is just playing mind games, he played everyone as to force maximum effort from the Warriors. Now they still think 73-9 is doable, so they will play hard in Memphis, and will be gassed for Sunday's game, which is the Spurs will win.
The fact the Spurs didn't play Miller or Simmons when GS had a big lead makes me believe wanted the Warriors starters to play as many minutes as possible.
