The Raiders revamped their wide receiving corps this offseason, bringing in Antonio Brown, Tyrell Williams, J.J. Nelson, Ryan Grant and fifth-round draft pick Hunter Renfrow to help quarterback Derek Carr.
Brown, Williams and Renfrow will get a lot of attention during organized team activities and minicamp, but there's another receiver who has impressed both head coach Jon Gruden and Carr early on in his NFL career.
Keelan Doss signed with the Raiders after going undrafted out of the University of California-Davis and has the size, ball skills and awareness to make it as a receiver in the NFL.
