The NBA on Monday canceled the first two weeks of the 2011-12 basketball season due to begin on Nov. 1, amid signs that additional weeks, if not the season itself, will likely be canceled unless some magical formula can be found to break the current stalemate between the team owners and the players. For the moment, cable television networks are likely to be hit hardest by the cancellation -- broadcast coverage ordinarily doesn't begin in earnest until around Christmas time, TNT had scheduled an opening-day doubleheader, beginning with the defending with last year's champs, the Dallas Mavericks, playing the Chicago Bulls, followed by the L.A. Lakers against the Oklahoma City Thunder.
