Cleveland Cavaliers coach Tyronn Lue wants to see a tougher tone from the defending champions in their do-or-die showdown Monday with the Golden State Warriors in the NBA Finals. The Warriors lead the best-of-seven series 3-1 but missed a chance to clinch with a 137-116 loss Friday at Cleveland, the more intense and physical Cavaliers ending Golden State's unbeaten playoff run at 15 games. "First three games we were being too nice, helping guys up off the floor, smiling, I didn't like that," Lue said Sunday.
