In fact there were some still willing to overlook Cooper Rush throwing 3 INTs against the Eagles, by claiming how he "almost" brought the Cowboys back in that game. Also despite the INT, Dak still made the throws he needed to make when the Bears started to close the lead in the 2nd half. And Dak lead TD drives in the 2nd half on offense which made it harder for the Bears to pull a comeback. Taking away the TD the defense got. The offense still managed at least 2 offensive TD drives in the 2nd half.
Some are willing to give Cooper Rush more of a pass for throwing 3 INTS against Philly in a loss, than they are willing to give Dak for an INT he threw in a game in which the Cowboys still won by 20 points. Dak still made up for the miscue by helping to lead a critical TD drive in the 2nd half.
