If Jamal Murray is concerned at all by the pause in contract extension talks with the Nuggets, he didn’t show it Wednesday. “When we get there, we get there,” Murray said after the Canadian national team’s exhibition in Las Vegas. “I’m playing games right now for Canada, so that’s not on my mind.” Canada jumped to an 11-1 lead but lost 86-72 to the United States in the friendly showcase game ahead of the Paris Olympics.
