New Portland Trail Blazers head coach Chauncey Billups questioned his team’s effort after a 114-83 loss to the San Antonio Spurs on Thursday night. The Blazers were without All-Star guard Damian Lillard but still put up little fight against a Spurs team which came into the contest six games below .500. “My biggest concern, I think, at the moment, is I want us to compete harder, man. I want us to compete harder,” Billups said. “I want us to be competitive in every game. And I don’t feel like every night we do that. We don’t. And it concerns me. And I’ve felt that way in a lot of our wins. This is not just after a loss, me saying this.”
