Garrett is a pre programmed robot so this will never happen, but the best option at this point is for the Cowboys to adopt a primarily read-option based offense ala the Lynch Seahawks, Kaepernick 49ers, and Panthers.
They follow the same checklist as these three teams. Mobile QB, subpar passer, subpar receivers (except maybe SF), great RB, and strong defense. I know it's a gimmick, but it's really the only way to maximize what they currently have with this group. If they were to actually get Earl Thomas and run this effectively (rofl a pipe dream) then I could actually see them fighting for a playoff spot with how inconsistent the NFC is as a whole
