Interesting take. It’s not only about the Dallas offense.
Despite the pick-six, I don't know if it's fair to say that Prescott had a horrendous game. He had some nice throws. It's just that this is a ridiculously good pass defense, and they appeared to be in Prescott's head from the beginning.
Dallas' passing game is mainly fueled by just how good and efficient Dez Bryant can be. With Bryant catching just seven of 16 targets for 59 yards, the Cowboys were forced to promote the rest of their receivers to more central roles that they just can't handle.
