A three-time all-state selection, the 5-10, 190-pound Marshall is also the West's top running back and a four-star selection in the Scout 100.
Several teams cover him and he's already got 15 offers with several more schools interested.
The Sun Devils have an advantage in that his older brother, Cameron, is a running back for Arizona State.
"There is a possibility we could play together, but I don't want to pick my school, and Cameron doesn't want me to pick a school, based on where he goes, but to find what fits best for me," said Marshall. "But I do like Arizona State. And it would be cool to play with him. We always talk about our careers. I tell him my high school career is going to be better than his, because he had a great career and it's something I strive for. He tells me I'll never be as good as him. We're really close."
In the meantime, Marshall said the two Bay Area schools are recruiting him the hardest, but he said no leader has emerged.
"I'd say Cal and Stanford are recruiting me the most, considering I'm in their backyard," said Marshall. "I've been to their campuses a lot and talked with the coaches more than other schools, so I'd say both of those schools are recruiting me the hardest."
Marshall said he's not focused on any one offense for college, liking several different types of offenses.
"I like single back a lot or the spread, being in the shotgun with the quarterback," said Marshall.
Marshall said he doesn't want to hurry the process, wanting to take as much time as necessary.
"I'm in no rush to see where I want to go," said Marshall. "If it happens soon, it happens soon. If it doesn't, it doesn't."
With his brother in Arizona, Marshall said his family is open to wherever he chooses to go.
"They just want to make sure which school I go to, wherever it is, it's best for me, whether it's close or far," said Marshall.
As a junior, Marshall ran for 1,632 yards and 23 touchdowns on 168 carries and also returned two punts for touchdowns, helping VC to the CIF-CCS Open Division finals.
