Schottenheimer said Feder brings him 25 to 40 situations from around the league each week, and that Dallas went for two at Philadelphia because the staff liked its quarterback draw.
Arizona has won eight of the last nine meetings, and Schottenheimer put the Cowboys at minus-11 in turnovers across those games before Sunday’s noon kickoff at AT&T Stadium.
Dallas has played two games at AT&T Stadium, four on the road, and one in Rio de Janeiro, and Sunday's noon kickoff follows three straight prime-time games.
Dallas acquired Porter from Pittsburgh on Sept. 30 for a 2028 second-round pick and a 2027 sixth-round pick after he sat out the Steelers' first three games.
