'You Question Everything -- Your Entire Career'.

SPIEGEL: Mr. Nowitzki, next to (German soccer star) Michael Ballack you are Germany's highest-paid professional athlete. This season you'll be earning a salary of at least $16 million with the Dallas Mavericks. And this spring you were voted the Most Valuable Player in the NBA. One could say that you are currently Germany's biggest sports star. All that, and you still haven't even won a championship. Why not?

Nowitzki: I won the Lower Franconia tennis championship when I was 12. Does that count?
SPIEGEL: Not really.
