John Wall is already a ratings draw in the Washington, D.C. market.
Washington Post sports blogger Dan Steinberg has the details:
The five Summer League games on CSN averaged a 0.83 household rating in the D.C. market, equal to nearly 20,000 households, according to Nielsen numbers. It doesn't sound like much, but bear in mind that the Nats last season averaged a 0.60 rating on MASN and MASN2. Hell, bear in mind that the Wizards averaged a 0.79 rating on CSN in 2008-2009, and a 1.16 last season. So yes, John Wall's Summer Leaguers outdrew the actual NBA Washington Wizards from two seasons ago, and the actual Washington Nationals from last year.
