The Minnesota Vikings are set to begin their quarterback story in the first preseason game against the Las Vegas Raiders. Sam Darnold, the presumed starter, will be tested alongside rookie J.J. McCarthy, who was drafted with the 10th overall pick. While Darnold has NFL experience, McCarthy's performance is expected to dictate his role on the team. If their performances are close, McCarthy may be given an opportunity to start early in the season.
