Justin Fields isn’t the first superior athlete at quarterback the Steelers have ever had. After all, they had Kordell Stewart, the great “Slash” player, and even Mike Vick for a short time. You can add Dennis Dixon and Joshua Dobbs to that list, and the Steelers found uses for their abilities.
That role extends into practice, which is ideal for the Steelers now because Fields is good preparation for today’s NFL. While mobile quarterbacks aren’t quite the norm, they are now quite common, and the Steelers see them quite frequently. That’s why defenders are talking about the benefits of practicing against him now to prepare for AFC North opponents.
