Scheme-dependent safety whose impressive pro-day numbers will earn a second look from evaluators. Teams will love the speed, quickness and explosive testing but the attributes don't always pop on tape. He's a little tight-hipped and lacks fluidity in man coverage and ball tracking as a deep safety. Nelson is instinctive and reactive when playing forward. He's a solid cover man over the first two levels from man or zone. He's a capable run supporter with quick diagnosis but can be inconsistent with pursuit angles. If used properly, Nelson has backup potential.
