Tim Twentyman
5. Duke, Thurs., March 28
Who to watch: Who is the best interior lineman in this draft class? Is it Oregon's Jackson Powers-Johnson? What about West Virginia's Zach Frazier? Michigan's Zak Zinter? Could Duke's Graham Barton be the guy?
Barton will get a chance to test and showcase his field work and versatility (played LT & C) in front of NFL personnel
