Not in love with Roy Devyn Marble but he's earning some love...— TheDraftReview (@thedraftreview) May 16, 2014
Draft Express has the shooting results for Marble (and everyone else at the Combine) here; he did well in the spot-up drills and not so well when he had to shoot on the move.
Our friends at the SBN mothership also managed to get an interview with Dev, which you can see above. Give it a watch! (YouTube version available here.)
