This is a great post from the painted area breaking down the X's and O's of how the Cavs are using LeBron offensively.

It focuses on using LeBron at the 4 in a UCLA double high post set and comparing his role there to Karl Malone and Chris Webber/Vlade Divacs.

It's extremely educational. Make sure to follow his links too, they'll lead you to even more insight on the breakdowns of the UCLA offense and LeBron's effectiveness from different sets.
