Well, it's the way Argentina defended Dirk back in 2002. It's a constant switch between Box-And-One, Triangle-And-Two, 2-3 Zone, and Man-To-Man to disrupt the offense rhythm.
Usually Box-And-One is used to defend a team that has one strong scoring option, which was the case of Germany. This defense is better to mark Guards (it was used on Iverson when he played in College), but with some modifications and smart players, it can be used on a big man who has Dirk's shooting range.
When in Box-And-One, Triangle-And-Two and Man-To-Man, Wolkowisky was man-marking Dirk. Pepe Sanchez was the other player man-marking, (to the German point guard) when playing Triangle-And-Two, but Germany lacked a third perimetral shooter scoring option, something that Dallas has. That lack of a third scoring option allowed the other 3 players to play a zone covering the paint (and they were 3 very good defenders and rebounders for FIBA standards: Manu, Nocioni and Oberto).
In Man-To-Man, if Nowitzky was matched-up with a smaller defender after a screen, Wolkowisky would still follow Dirk even if that meant double-teaming him in the perimeter, leaving a German player open for a shoot or a penetration (if Dirk could pass off the double team). But just for a second because the defense would help and rotate, leaving the Germans with the only option of a risky skip pass to the weak side.
2-3 Zone was used briefly when Nowitzky was posting-up, with Nocioni or Oberto helping Wolkowisky on the weak side, or Manu going for the steal if Dirk was trying to back down. Again, the lack of shooting options prevented the kick out.
If you understood anything of what I just finished typing, I congratulate you, because I don't know if it made any sense! Do you speak Spanish?
