Clemson offered a more inviting depth chart. Starter Andre Ellington will be a senior in 2012.
The Tigers also offered a strong bond that had developed between Marshall and Clemson's players, including freshman receiver Sammy Watkins.
"The players I knew, Sammy and all those guys," Marshall said when asked what he liked about the Tigers. "They're really cool people. I really like the coaches there and the atmosphere. It was a hard choice."
Marshall said he called coaches from all the schools that he was considering just hours before his announcement.
