Marshall has been a stalwart in the Jackrabbits secondary for the past couple of years, yet he's just now entering into the prime of his recruiting and with 51 weeks until Signing Day, already is in the 20's for offers.
"I'm at around 24-25 offers right now," said Marshall. "I'm really excited for this recruiting process. It's a once in a lifetime experience. I want to take it in as much as possible."
Marshall boasts offers from programs like Arkansas, Florida State, LSU, Michigan, Mississippi, Nebraska, Notre Dame, Oregon, Tennessee and Wisconsin, plus all four in-state Pac-12 schools and said a couple of national programs stand out.
"Florida State, the national champs, Notre Dame, Michigan, Tennessee and LSU are some of the big national ones," said Marshall. "Alabama is supposed to offer soon and I like them too."
From the Pac-12, Oregon is the one out-of-state program that has his attention, plus Stanford and the two local schools.
Marshall was at USC's Junior Day earlier this month, the Trojans his childhood favorite.
"I went to USC for their Junior Day and I enjoyed myself," said Marshall. "I love the new coaching staff. They're great, they're young and I like Coach Sark (Steve Sarkisian). USC is definitely high on my list. Now Juju (Smith) is going there so they have some guys I've played with."
Marshall plans to also visit UCLA soon.
"I'm going to head up to UCLA real soon, maybe this weekend or next and I'll be up at their Junior Day," said Marshall. "I like Coach Meat (Demetrice Martin) and Coach (Jim) Mora a lot."
Stanford, which last signed a player from Long Beach Poly in the 90's when former quarterback Chris Lewis inked with the Cardinal, offered Marshall and that offer left a big impression.
"My family was really excited and proud of me getting that offer," said Marshall. "It shows that I'm a true student-athlete when Stanford offers. My dad has always made me work hard in school."
Marshall said that with it now being time for the 2015 class to take center attention in recruiting, he's fully realizing a childhood dream.
"It's my time now," said Marshall. "I've been waiting for it since I was a little kid. I didn't think it would be this big. I never thought it would be to this extreme. I thank God for putting me in this position, and my family and my parents for their support."
Having seen several teammates go through the recruiting process, including Smith, who like Marshall, was a major national prospect and decided on Signing Day, Marshall doesn't plan to rush into a decision.
"To be honest, I'm going to try and wait it out, take the trips, enjoy the process and go as long as possible," said Marshall. "Now if I find the best one early, I'll go ahead and commit but if not, I'll wait it out."
Last spring, Marshall was arguably the top defensive back at the Los Angeles NFTC, despite being an underclassmen and earned an invitation to The Opening, one of just five juniors selected to the event. His goal is to get back.
"That was an amazing experience and I want to get back to The Opening," said Marshall. "We're also doing more 7on7 this year (with B2G), so I'm just ready to get back out and play."
Much has been made about Marshall's size and how safety could be in the cards for him, but Marshall remains adamant about which spot he'll play in college.
"I'm playing corner at the next level," said Marshall. "That's what I play, that's what I want to do and that's where I'm going to be."
