He wasn't talking about professional teams, he was talking about the talent coming out of the City and saying Chicago, not New York, should be treated as the city producing the most talent.
And you do have a pretty darn good team all time with players from Chicago including Isiah Thomas, Dwyane Wade, George Mikan, Tim Hardaway, Mark Aguirre, Dan Issel, Mo Cheeks, Antoine Walker, Doc Rivers (and others) all coached by Mike Krzyweski and of course current players like Davis, Patrick Beverly, Jabari Parker, Derrick Rose. Lots of talent has come from Chicago.
