Friday Oakland camp notes

Posted by ESPN.com's Bill Williamson

NAPA, Calif. -- The Oakland Raiders continued their slow-motion beginning to training camp in Friday's morning session.

The practices are glorified walk-throughs. The coaching staff is emphasizing teaching. Thus, the practices are more of an extension of the offseason than training camp. The Raiders, who started to practice Thursday, will continue this teaching session twice a day through Sunday. The hitting portion of camp begins Monday.

After the morning session, Oakland coach Tom Cable said he wouldn't be surprised if his team is raring to go when it's time to hit Monday. Cable said several players are asking questions on the field and he sees great benefits coming from the sessions. Cable said he used the same approach as the head coach at the University of Idaho.

Some of the players were skeptical when they were told of the plan in a team meeting Wednesday.

"I was wondering about it, but I really like it," said cornerback Nnamdi Asomugha. "It's about learning. We're really figuring things out."

Meanwhile, defensive tackle Tommy Kelly continued to have trouble with jumping offside Friday morning. He jumped offside three times Thursday and once Friday morning.

Cable said there is competition at right cornerback between starter Chris Johnson and Stanford Routt.

Receiver Javon Walker intrigued reporters Friday by saying he had an innovative medical procedure on his knee. Yet, he offered few details. Walker said he will reveal the details after he reaches the practice field, which he expects in a couple of weeks. Walker had offseason knee surgery.
