So that quote is really out of context and it implies things that the full quotes don't. The full quotes are:
“My defense lacks at times,” Dillingham said. “But I feel like when I actually give effort and I know the game plan, then I really know what to do. Sometimes, I don’t know the game plan, and it gets me off, so I’m halfway going. But I feel like when I actually know the game plan, I’m a great defender, when it comes to being on the ball and terrorizing the ball.”
“I feel like in college, we weren’t all the way locked in on defense,” Dillingham said. “So we would all be thinking different stuff, so we’ll play it different ways. And it would look like, ‘Oh, he’s not playing defense.’ But we really think we’re playing the right defense, you know?
