Each program will receive an official visit during the month of October according to Marshall, who has also received interest and offers from Northwestern, Baylor, Boston College, Florida International, Memphis, and Rutgers. In the meantime he's working on improving.
"I need to continue to work on my footwork and my timing. It's something that is so important to being a quarterback."
Marshall knows all about being a highly rated signal caller. In fact he's probably one of the top dual threat options on the Duke recruiting board. So what makes this three star prospect so dangerous?
"I think I'm a dynamic player. Anything my team needs, I'm going to do it. If they need me to throw it or make plays with my legs, I'm going to go make that play."
A few weeks back, Marshall was able to display his dynamic playmaking ability in front of the Duke coaching staff at the Blue Devils' quarterback college. The experience was something that seems to have left an impression.
"I got to workout in front of Coach Roper and Coach Cutcliffe. They really know their stuff. The quarterback college was more than a camp. After we did drills we would go up into the media room and watch the tape of the workouts to see what we did well and what we did wrong. Those guys can teach you something that others may not because of their experiences. Coach Cutcliffe has coached the Mannings and they come back to workout with him during the summers. Getting a chance to play for him would certainly be an honor."
Of course there are a number of obstacles between Marshall and the potential of playing in Durham. Some he can control, and others he can't. For instance, there are three other finalists that are neck and neck with the Blue Devils in this race. And there's the recent commitment of QB Thomas Sirk to Duke to deal with.
"Each of those schools has great academics and are really good programs who like to throw the ball around. I feel like I could be successful on and off the field at any of them. I know a degree from those kinds of schools would set me up for life after football ends."
And the recent commit of Sirk?
"Honestly the coaches at Duke haven't talked to me about it, but it isn't a big deal in my mind. If I have to go in somewhere and complete to win a position, or to beat someone out….then I'll do it. I've been proving people wrong all my life."
Marshall is rated as a three start prospect and the No. 49 QB in the country according to Scout.com.
