Rookie WR Keyshawn Martin has quickly stood out as a return specialist in the eyes of coach Gary Kubiak. Martin produced 1,759 return yards at Michigan State while also scoring on both punt and kickoff returns. Kubiak added that WR Trindon Holliday has made strides at the position; while his return skills are a strength, Holliday must continue to show he can be an effective wideout in order to assure himself a roster spot.
