Does Dirk need a title to prove his worth?

DALLAS -- Dirk Nowitzki knew the question would come up. It always does. It has to. And Mike Greenberg of ESPN Radio's Mike & Mike Show did the honors Wednesday morning when Nowitzki joined them on the American Airlines Center floor as part of the 10-year anniversary celebration of 103.3 FM and a decade of broadcasting Dallas Mavericks basketball.

Greenberg asked Nowitzki, after coming so close to winning it all in 2006, how would winning a championship change the way he is viewed around the NBA.

"It would definitely help," Nowitzki said. "But, also there are a lot of great players that never had the chance to win, so I don't think I would be in bad company there. But, it's definitely the only thing I play for now. Coming over from German, nobody really expected me to do anything here, so I've achieved a lot of great things with All-Stars and MVP and a lot of great things, but really the only thing I play for now is to win it all. I signed on for four more years, and I still feel good, I still feel like I'm in my prime, so hopefully in these next couple of years we can get it done."

Golic then asked Dirk if he'd view his career as unfulfilled if he doesn't get that elusive championship.

"For me, a little bit probably because I keep thinking about the '06 Finals, being up 2-nothing, everything was in our way and not to come up with that ring that was very disappointing," Nowitzki said. "And it probably will be for the rest of my life if I don't have the chance again. So, I'll be thinking about that lost opportunity."

So, what do the Mavs have to do this postseason to get the ring?

"We got to get back to playing defense like we did in November, December," Nowitzki said. "We had a great run there and won a lot of games there, won a lot of big games, so we got to get back to that...Offensively, I think we'll be OK. We've got to move the ball, we've got to make shots. Jason Kidd's got to step up. Jet [Jason Terry] and myself have got to play big and some of the other guys have to make shots. Everybody knows we're more of a jump-shooting team, we're not a pound-it kind of team. We've got to get some stops so we get the ball moving on offense and speed the game up some. If the game slows down, it's really a knock-down, kind of drag game, it's never in our favor."
