The 6-foot-4, 275-pound Marshall runs the 40-yard dash in 5.2 seconds.
"It was just an all-around good place for me. I really liked Lubbock a lot and I had a lot in common with a lot of the guys on the team, I felt like I fit in. It was a nice environment out there."
While Marshall is excited about his decision it will be tough to tell others no.
"I'm going to hate making that call to Missouri, because I really like their coaches and everything. I felt like I should stay in state and this going to be a lot easier on my mom too."
Marshall says he will not be taking any more visits.
"I wanted to make sure that I was going to be happy for the next four years of my life and in Lubbock I know that I will be."
