One factor, Valentine said, in choosing the NFL related to former Nebraska defensive line coach Hank Hughes. Before Valentine made his decision, he talked to coach Mike Riley about Hughes.
"When I was talking to Coach Riley, he kinda seemed like he was sticking with Hughes," Valentine said. "I didn't think they were going to change it, but it happened. I was hearing it happened because of the recruiting trail, but I'm not sure what happened. I was kind of surprised that they changed."
Riley fired Hughes in early February.
Valentine said he shared his concerns with Riley at the time.
"I didn't think he was as great of a teacher as I wanted him to be," Valentine said of Hughes. Valentine said Hughes' predecessor, Rick Kaczenski was a different kind of coach and more into details.
"That's the reason I didn't think I'd improve my draft stock," Valentine said of Hughes potentially returning. "That wasn't the biggest factor in (the decision), but I think it was one of the factors."
