The 5-foot-10, 195-pound Marshall said he would like to make an official visit to South Bend, Ind., for the Irish's game against USC on Oct. 22, even though his team has a 7:30 p.m. kickoff the night before in the Bay Area.
"I talked to Notre Dame about taking an official visit for the game they play USC," Marshall said. "It's not set in stone, but if I were to take an official visit there, because I really want to, that would be the game to go to.
"They said it's their first night game at home since 1988. There's a red-eye that leaves at 11:55 p.m. out of San Francisco, so I'll probably catch that."
Marshall's visit to campus allowed him to see Notre Dame's program in a different way than when he talks to the staff on the phone, and his face time with coach Brian Kelly was important.
"I didn't go out there with the mindset of expecting anything, but it blew me away, from what I saw," he said. "I learned a lot about the school. I knew they had a great tradition, were a real good program and coach Kelly was a real good coach, but I got to learn more, in-depth, about everything.
"I talked to coach Kelly 1-on-1, and I got to learn a lot more about him like where he comes from, how he operates. I got to see how their practice is, and the tempo they go at, and the academics of the school, and how they operate with academics. I got to learn everything about the school."
Marshall also found out how much the Irish want him.
"They told me, ‘That out of all the players, you're the No. 1 player we want,' " Marshall said. "It wasn't as a running back, but as a player. I'm happy. It feels good to be wanted. I think it's real cool they feel that way."
Marshall capped a busy two days with a trip to nearby Purdue.
"They have great academics in Purdue, one of the best in the nation," he said. "They have a team they're trying to build up. They're trying to get a lot of speed. They said they have 18 guys that run a 4.5 or under. They have three linemen that are 6-6, 6-7, 6-8. It would be great to run behind those guys. They said they wanted me badly also."
