I noticed the same thing Neal Pollack did:

As the Sox cruised toward their destiny tonight, with one out in the 9th, Mr. Buck started naming off South Side neighborhoods. He got them right: Bridgeport, Hyde Park, Back Of The Yards, and a couple of others. He then mentioned how the South Side is home to many different ethnic groups: Irish-American, Polish, Lithuanian....and then he stopped.

How in the world can a grown man in the sports business talk about the South Side of Chicago and possibly not mention that black people live there? Or hundreds of thousands of Mexicans? Or, you know, people from non-Caucasian ethnic groups.
