The Chicago Bulls have overcome defensive struggles to stay atop the East. But they know they need to quickly improve as opponents continue to pummel them in the paint.

“When it’s great and you’re able to be in the right spot, then you’re most likely going to be able to do a good job,” Vučević said. “When it’s not, you have to figure it out. That’s where it’s scramble mode. If I get beat, then another man is there. If a screen gets hit, then I’m there to help. It’s just covering for each other.”
