Former All Pro return specialist, Joshua Cribbs, went unsigned this off-season due to concerns about his surgically repaired knee which he injured last season. According to Ian Rappoport, the Raiders gave Cribbs a physical - of which he passed - and extended him a contract offer, but he left without signing.
Cribbs is currently weighing his options as three other teams have also shown interest in acquiring him. He has more visits scheduled, the Jets being among them, before he makes his decision.
If the Raiders can reel him in, he would solve their return issues as well as strengthen their receiving corps. In eight NFL seasons, Cribbs has made two Pro Bowls as a return specialist and named All Pro once. He is also a decent receiver who has shown the ability to stretch the field due to his tremendous speed.
Cribbs has returned both kicks and punts in his career. The Raiders currently have Jacoby Ford to return kicks so it Cribbs could fill the void at punt returner.
