I just finished reading Dave Zirin's What's My Name, Fool?. Very insightful writing about sports, protest & politics from a Mac '96 lad. Getting a blurb from Chuck D does a lot to make me forget the chicken-leg-in-the-pocket episode.
His newsletter tipped me off to Wizards forward Etan Thomas's new column on Slam: http://slamonline.com/online/2006/11/type-casting/. It provokes a very animated debate about racism, classism and ismism. Worth checking out, so long as you can handle the indifferent spelling, logic and grammar of most commenters.
