Prescott, Cowboys out to answer bell vs. Lions

On Sunday, they hope that begins to happen when the Detroit Lions visit AT&T Stadium. In order for quarterback Dak Prescott to develop chemistry with new receivers like Tavon Austin, Allen Hurns and Deonte Thompson in games, a lot of other things have to go right.
