ALAMEDA -- The signing of cornerback Joselio Hanson and departure of DeMarcus Van Dyke Monday makes it a clean sweep at cornerback.
The Raiders have six cornerbacks on the 53-man roster and none were with the team last year.
"As things played out throughout minicamps, OTAs and then training camp, we felt that was a position that we needed to try and upgrade and we felt like with the players we brought in, it helps us as a team to be better," coach Dennis Allen said.
Only Chimdi Chekwa, who cleared waivers and was placed on the practice squad, still is with the organization.
"I looked around the (meeting) room this morning, and the only one left was Chim," safety Michael Huff said. "It's a new regime. We were braced for change."
A seven-year veteran, Hanson (5-foot-9, 185 pounds) gives the Raiders an experienced slot corner to go along with Huff, who last season played in the nickel defense against slot receivers.
"I have so much experience in the slot it's like second nature to me now," Hanson said.
Hanson admitted he was "shocked" at being released by the Philadelphia Eagles, in that he was the nickel back with the first team throughout the entire preseason. He also said he was happy to join Oakland -- he also talked with Miami and Seattle -- having grown up in Southern California a Raiders fan.
Van Dyke's confidence level seemed to fluctuate based on his confidence level. Speaking with Van Dyke after his release,
"I'm sure this will make him stronger, a better man and a better football player," Bartell said. "He'll definitely get a chance, he's such a talented guy."
"We didn't have any Kumbaya moments," Allen said. "It was time to roll."
"He moved around a little so that was good," Allen said. "I would expect him to be fine for (Thursday)."
Wide receiver Juron Criner was practicing with a bum ankle and was noticeably affected by it, but Allen said, "It's a long time until Monday night. We'll be fine there."
"He's a smaller linebacker who can really run," Allen said. "I'm looking for him to do some good things for us special teams-wise initially to start us off."
