The South Florida Sun-Sentinel (Dave Hyde) writes: Most days, Erik Spoelstra opens practice with Tupac Shakur rapping in the background, which is the Heat coach’s way of finding someone to “motivate the motivator,” as mentor Pat Riley says. Tupac motivates Spoelstra. “He’s of my time,” he says. It’s an interesting storyline if you freeze it there, the young coach relating to hip-hop players in a manner few NBA coaches do. Early on, Heat players took it to mean their new coach might be one of them, and lobbied for other, newer music. “Then they found out I only liked Tupac,” Spoelstra, 37, says.
