Before Nebraska (Cardinal Mooney HS)
Marlowe was one of the final additions to the 2008 Nebraska recruiting class, committing to the Husker program the week of signing day. Marlowe was the first player from the state of Ohio to commit to the Husker program in 10 years. Marlowe showed his versatility as a senior at Cardinal Mooney High School, beginning the season at receiver, before being pressed into service at quarterback and leading his team to the state championship game. Marlowe also continued to play a role on the Mooney defense.

Marlowe ran for almost 300 yards on 42 carries and scored four touchdowns. He also caught nine passes for 216 yards and three more touchdowns. On defense, he had 36 tackles, led his team in pass deflections with 32 and in interceptions with five. He also had three kickoff returns for 70 yards. His play helped Cardinal Mooney and Coach P.J. Fecko to a 14-1 record and a Division IV state runner-up finish. In the state title game, Marlowe rushed 17 times for 104 yards and a touchdown, completed 5-of-6 passes for 135 yards and a touchdown and made three tackles on defense. Marlowe was also a two-way standout for Cardinal Mooney as a junior, helping the Cardinals to a perfect 15-0 record and a Division IV state title.
