And the four-star will head to Eugene for the Civil War as the newest member of the Ducks' recruiting class, committing to the Ducks on Tuesday night.
Marshall, who had offers from all over the country, including the whole Pac-12, picked the Ducks as Valley Christian prepares for the CIF-CCS playoffs.
"I'm excited about this and I felt like Oregon is the best fit for me," said Marshall.
Marshall told head coach Chip Kelly that he wanted to be a Duck, and is thrilled to be heading to the two-time defending conference champion, and the favorite to win the conference again.
"Oregon is a place that I can be successful and I'm excited and looking forward to what is to come," said Marshall.
Marshall was supposed to visit Cal next month and Oregon later this month, but will just visit Oregon.
"I'll be visiting Oregon Thanksgiving weekend," said Marshall.
Marshall felt like now was the best time to decide.
"I committed now just because I didn't want to draw this out any longer," said Marshall. "I feel happy with my choice and feel like this is the best place for me so there was no need for me to wait any longer."
