That's dumb showing the Thanksgiving day off network. They are messing with a tradition that earned them more than immediate money.
They could be shooting themselves in the foot. Thanksgiving used to be a big college football rivalry day before the Dallas Cowboys started playing on Thankgiving back in 1967. If football fans were given the choice between Texas A&M vs Texas on network TV at the same time that the Dallas Cowboys are on pay per view, which game do you think would have higher ratings?
