Denver Nuggets coach George Karl wouldn’t reveal the contents of his motivational halftime speech on Saturday night. “I don’t know if most of it is printable,” he said.

The Nuggets, who trailed by 25 points in the first half, used Carmelo Anthony’s 32 points and 10 rebounds to pull out a 113-106 victory over the stunned Indiana Pacers.
