The New England Patriots' shot at history Saturday night will be available for every household in the country with a television after months of wrangling. The game against the New York Giants, in which the Patriots could become the first NFL team to go 16-0 in the regular season, was originally scheduled to be shown only on the NFL Network which is available in fewer than 40 percent of the nation's homes with TVs. The league announced Wednesday that the NFL Network feed will be simulcast on NBC and CBS. It's a major concession by league officials, who repeatedly said they would not show the game anywhere but the NFL Network. The NFL had faced mounting pressure from lawmakers in recent weeks to make the game available to more viewers. Local TV affiliates in the Boston, Manchester, N.H., and New York areas who were already set to simulcast the game under NFL policy and will still air it.
