Cavaliers coach Byron Scott blasted Kyrie Irving’s defensive effort in the Cavs’ 39-point loss to the Bulls on Friday.

“The defense starts with him,” Scott said. “He’s the head of the snake and I know it’s a lot of responsibility for a 19-year-old, but it is what it is and he’s got to do a better job. And he’s aware of it.”

Irving leads the team in scoring, but Scott said that mindset has to change immediately.

“He had better coast on offense,” Scott said. “I made that point not only to him, but everybody. If you are going to rest, you rest on the offensive end. You’re not resting on defense.”
