(Chicago, IL)  --  The first round of 2015 NFL Draft takes place tonight from Chicago's Auditorium Theatre.  Several former Oregon Ducks are projected to be selected over the next couple of days.  Heisman-winning quarterback Marcus Mariota projects the highest, and could very well be the top pick in the draft.  Defensive end Arik Armstead and center Hroniss Grasu also are expected to be selected in the first few rounds.
