Moss can be effective over the middle as seen in his senior year at Miami. But anyway, Ginn's highlights are almost all him going deep but if you have the tapes on his games in their entirety, he was across the middle quite a bit. Tough kid too who will put his body out there and grab the ball. Putting him in the middle would really open up things downfield for Plax because his presence will always be on the minds of safeties, his speed is that unreal.
Plus, his return ability alone could be argued for 1st round credibility, many think he is better than Hester in that regard. Just keep that in mind.
