Head coach Mike McCarthy stated on Wednesday that the team will be going with Garrett Gilbert or Cooper Rush, benching rookie Ben DiNucci after struggling against the Philadelphia Eagles.

The Cowboys are simply a mess without Dak Prescott under center and the defense has not performed well since Week 1 against the Los Angeles Rams.Unless McCarthy has some sort of huge plan to dethrone the Steelers with Gilbert under center, the Cowboys are in for a show playing against Ben Roethlisberger and head coach Mike Tomlin's defense.Prediction: Steelers win in easy fashion.
