Dirk Nowitzki with Holger Geschwindner

Mavericks superstar Dirk Nowitzki joined KRLD-FM 105.3 to talk about the documentary - Nowitzki. The Perfect Shot - that is making its U.S. premiere at the Dallas International Film Festival ... and other topics. Here are some highlights.

Holger used to be a beast on the court, how good was he?

Dirk Nowitzki: I think, at the beginning, the first 30 minutes is very Holger heavy. But it obviously makes sense, to come around, the way they bring it back over the basketball, his music, how his philosophy is with hoops. Obviously, without Holger I wouldn't have had the career, I might not have even made it to the NBA. It's well deserved. He's got a nice little chapter in there.

I wish we would have seen a picture of his closet, so I could see the 50 leather jackets all on hangers

Dirk Nowitzki: Wait, there's only one. Every time he comes here, everybody is like, 'Isn't that the same shirt he had on when he was here a month ago?' And I'm like, 'yeah, pretty much.' One day, I think we were still with Avery, we're in the middle of the playoffs, we're prepping down on the practice court and Holger walks in on the practice court, up on the catwalk. I think he had a new shirt on, some new jeans. He walks in; everybody looks up and says 'Oh, my God ... Holger's got a new shirt on.' Avery had to stop practice.
