And once the 6-foot-2, 180 pounder told head coach Ted Roof that he was indeed set on becoming a Blue Devil, the Duke coaching staff wrapped up one of the top two receiving prospects on their recruiting board. Though Marcelin is a virtual unknown to many recruiting services, that wasn't the case when it came to top coaching staffs.
"I had interest from Wake Forest, Northwestern, Mississippi, Mississippi State, Miami, and a lot of other regional schools. All of them were recruiting me as either a free safety or receiver."
At Duke his position is still up in the air, though the smart money is on adding him to a young and talent crop of receivers – which is just fine as far as Marvin's concerned.
"I can play wherever they need me to play. I'm going in with an open mind and will be open to trying whatever they ask me to. I think I'll be able to catch on. The one thing I'm concentrating on at this point is strength and speed."
Not that he's lacking speed after clocking a 4.5 forty as a junior while leading Hollywood Christian as both a receiver and free safety.
His statistics aren't great on the offensive side of the ball, but that's because Hollywood Christian lacks a decent passing attack, preferring to grind it out on the ground. Still he managed an impressive 10 catches for 170 yards and three touchdowns as a junior.
Those numbers will likely go way up when he arrives at Duke and is integrated into the new look Blue Devil offense complete with top rated quarterbacks and a higher level of talent.
"That's what is exciting about Duke. Turning a program around starts with recruiting better talent. This class is looking really promising for them in the future, and it's great to be a part of that. I really think we're going to turn things around there."
Off the field Marvin has already fully qualified academically and says he will likely go pre med while in Durham.
