There's nobody quite like Ravens quarterback Lamar Jackson in the NFL.
There are mobile quarterbacks, but they don't have that kind of agility and speed. His unicorn nature is why Vikings coaches enter Sunday's game in Baltimore having slightly altered the pieces at practice.
Third-round rookie quarterback Kellen Mond ran for 1,609 yards at Texas A&M. While Mond has been the scout-team passer this week, running the Ravens' equally unique NFL playbook for the Vikings defense, they've at times swapped Mond out for defensive backs Parry Nickerson and Tye Smith. They're the faster athletes, and theoretically tougher to catch in the open field while preparing for Jackson, the 2019 NFL MVP.
