Aikman on Prescott's accuracy: I've seen too many errant throws

Dallas great and Hall of Fame quarterback Troy Aikman knows what Dak Prescott needs to do to improve. The 25-year-old Cowboys quarterback's 61.8 per cent completion rate is good for 28th in the league, one spot in front of Jacksonville Jaguars quarterback Blake Bortles. Prescott is 24th in the NFL with 961 passing yards this year.
