Oakland should be happy with its first-round rookie for years to come.

But not every Raider can contribute like Amari Cooper has -- or even crack the playing field.

The Alabama product is the team's only rookie starter. Other rookies -- like second-round pick Mario Edwards Jr. -- are only rotational options through four games.

Third-round pick Clive Walford was slated to contribute like Cooper. Then, he suffered a summer injury and fell behind fellow tight end Mychal Rivera on the depth chart.

The team's fourth-round pick, guard John Feliciano, hasn't been active for a game yet. And later-round picks have only played sparingly as special teamers.

All this could change as young players adjust to NFL life. But as it stands now, the Raiders 2015 draft class is a one-man show.
