but i think you're getting him mixed up with Sammy Watkins.
Martavis in 3rd round would be awesome for him. He's still raw and needs to learn technique and consistency. Technique would help with his consistency of course. But his potential was never reached here at Clemson. Maybe it was that he was overshadowed and didn't get the opportunities that hopkins and watkins recieved but it will be tall order to show out in the NFL.
Definitely has the size and speed to be a star but will need to get it together before guys like darelle revis and richard sherman are in his ear and busting him at the line of scrimmage.
