Two games later, Marshall received his first scholarship offer - from North Carolina.
"It was exciting, but I didn't know how to take it," said Marshall, whose father played a season for the Denver Broncos.
Marshall now has approximately 20 scholarship offers, including Alabama, Auburn, California, Clemson, Duke, Florida, Georgia, Georgia Tech, Maryland, Notre Dame, NC State, South Carolina, South Florida, and Southern Cal, in addition to UNC.
"He has the talent and he also has the GPA that everybody's looking for," Inscore said. "He's a good kid from a good family. He works hard – he's always striving to be the best no matter what he does.
"He's just a dynamic runner. He reads blocks well. He has good cut back vision. He has great power and strength. And of course he has incredible speed. Once he's in space, it's hard for the defense to tackle him."
With so many options, Marshall plans to make as many visits as possible, including most of his official visits, before deciding.
"I plan on graduating early, so I won't be able to wait until Signing Day [to make my decision]," Marshall said. "But whenever I feel I know what school I want to go to, then I'll make my decision."
Marshall has already made visits to Alabama, Clemson, Florida, and South Carolina, and has been to both Georgia and UNC a few times.
"[I'm looking to see] if I like the atmosphere, the players [and] see how they get along," Marshall said. "I look at the coaches too, but I can't really focus on that because they might be gone – you never know. And I look at academics, too."
To make the situation more manageable, Marshall is considering narrowing his focus to five to ten schools by the end of the spring.
"There are a few schools I like in the SEC and I like UNC a little bit," Marshall said. "But I don't have anything solid yet."
Several factors have UNC firmly in the mix for Marshall.
"I like the coaches – I talk to them a lot," Marshall said. "They were the first school to offer me. It has good academics and it's close."
He said a negative with UNC is the lingering NCAA investigation.
"I want to see what happens with it," Marshall said. "I don't want to go to a program that's in a whole bunch of turmoil. But if it's not that serious then it won't affect me."
While on the recruiting trail, Marshall has developed a relationship with fellow blue chipper Ronald Darby from Oxon Hill (Md.) Potomac.
"I talk to [Darby] a lot," Marshall said. "He and I are trying to look at the same colleges. We wouldn't mind going to the same college."
In two seasons as a fulltime starter, Marshall has rushed for 2,716 yards and 19 touchdowns.
