Dak Prescott has started for America's team since 2016, and in that span, he's led Dallas to a 37-20 record with a 66.5 completion percentage and a 97.1 quarterback rating. It seems unlikely that Jerry Jones would divert away from his quarterback at this point. However, Prescott's backup, Cooper Rush, does not have much game experience to this point, so Kaepernick would be a much more seasoned option to step in should anything keep the Cowboys' QB1 off the field.
