With the Spurs down by two points and the game clock running down Danny Green went and committed a foul.  That wasn't the plan.  As you'll see in the video Spurs head coach, Gregg Popovich, was trying to tell Green not to foul.

As you'll also see in the video, Popovich went off on Green.  This is the same game from earlier in the week that Popovich sat Tony Parker for poor play.
