But now Clowney must convince coaches, scouts and team executives the guy they watched in 2012 was the same guy they saw on film in 2013 and will continue to be the same guy they can build a defense around.
And to jump back up the draft board into position for the top spot, Clowney understands he has to convince teams he means what he says.
"I just want to be the best, one of the greatest of all time," he said. "Coming out of high school, I said I wanted to be one of the best in college and I think I proved that. Going to the NFL, I want to be one of the best in the NFL, go down in history as one of the best, so I have another stepping stone in my way and hopefully I can take care of business and accomplish that in the NFL."
