According to Dallas Mavericks owner Mark Cuban, Luka Doncic is adding something "insane" to his game this offseason. In an interview with Bleacher Report's Taylor Rooks, Cuban said that we'll know it when we see it:

Rooks: "When I spoke to you after the bubble, we were talking about Luka for a little bit and you said that you'd asked him, 'OK, what are you going to add to your game this offseason?' And at that time it was that he wanted a left hand and he wanted to be able to finish. And that was what he added in the bubble season. So have you asked him that question yet?"

Cuban: "Yup. But I can't tell you."

Rooks: "What? Why? You told me last time."

Cuban: "No, I can't tell you. But yeah, it was crazy what we talked about adding. And so we'll see. I don't want to jinx him. But if you see something, you're going, 'Where the hell did that come from?' you'll know that's what it was."
