John Calipari discussed the injury history of Derrick Rose during a radio interview on Wednesday.

Calipari coached Rose during his lone collegiate season at Memphis.

"I coached Derrick, so here's what I know. He will defer to his team. Now I will say this, and he knows this, he doesn't have a real high pain threshold," Calipari said. "He's one of those guys, and while he's getting injured, he knows 'I gotta be right.'  

"When you're an athlete like Derrick Rose, it is really important that you're healthy. He's beating you with speed, with explosiveness. And if I'm the Bulls, I don't want him at 70 percent. We gotta get him at a 100. But it was a freak hit to his eye."

Rose suffered the eye injury during training camp.

"It was a freak hit," Calipari said. "Let me say this: They're going to win because of Derrick Rose. You watch."
