We spoke with Marshall at the Las Vegas Easter Classic and asked about the schools that have been in contact with him.
"My coach is handling it, so I don't really know much about what has been happening," said Marshall. "But some of the schools that have been in touch are Kansas, UCLA, UNLV, Iowa State, Washington, Notre Dame and Stanford. I don't have a favorite right now."
We asked Marshall if he has given much thought to the factors he'll consider when choosing a college.
"I'll probably be looking at which schools are strong in my major," said Marshall. "I don't know what that will be, but that will be important. Early playing time will be a factor. The location, though, won't be a big deal. My parents want what's best for me. They'd be happy if I was close, but they'll want whatever is best for me."
Marshall has yet to visit any schools, other than the local school UNLV.
We asked Marshall if he had any favorite schools growing up.
When questioned about the timing of his decision, Marshall said, "I don't really know – it will depend on which schools are showing interest in me."
We asked Marshall how he's doing academically.
"It was a 4.0, but now I have a 3.7 GPA.," said Marshall.
