I like your thinking here because when a defense has to scheme to cover a good running QB it usually leaves other areas more vulnerable. The hawks themselves have been burned many times by good running qbs.I’d be more than OK with QB rollouts and let Marco wing it or run every pass play over another year of an immobile fence post in the pocket.
Usually a rollout cuts down the area of the field you want to throw into but a strong armed qb can overcome that. As others have said, if Marco and Hill are basically even in most other respects then Marco should be ahead of Hill based on his running ability.
