Not saying Duane will light the league on fire, but I think he is far better suited to have an early impact as a scorer than Derrick. Derrick scored in HS largely because of his strength/size ratio. He played like a running back, scoring through contact. Guys at that level simply didn't have the strength to stop him. At this level, everyone is bigger and stronger, making it harder. Duane is a better perimeter player and has more natural scoring moves.
I still think if we get a scoring spark from a freshman it will more likely be Jajuan Johnson, and if any of the recruiting gurus (Ted, IWB) want to correct me on this they certainly know more than I do about these guys coming in, but I just feel Duane's skillset is better suited to acclimate quickly to D1 ball.
