Walker opened the 2004 season at right tackle, only to have a difficult game in pass protection in the season opener against Pittsburgh. He was benched in favor of top draft pick Robert Gallery.
He moved somewhat reluctantly to left guard last season, where he started until suffering an intra-abdominal hemorrhage after six games and missing the rest of the season.
"The way things have gone, I've played guard, played either tackle, so it's pretty obvious my athletic ability has allowed me to excel at any of those positions except center," Walker said.
He is back in the starting blocks for good, according to coach Art Shell.
"He's a defensive end," Shell said in officially ending a two-year experiment of using the 6-foot-6, 275-pound Colorado product at outside linebacker. "When we told him, he was excited about it. Get back down and get after the passer from that three-point stance."
Not only was Brayton back at end, but he worked extensively with the first time from the right side during the Raiders' three-day mini-camp.
"It was my first experience and he scored on me," Huff said. "But that's part of the territory, so I've got to go out there and get better every day."
Based on the first mini-camp, Huff will be used much like Woodson was -- as a versatile defender capable of playing deep safety, blitzing, covering receivers in the slot or taking players man-to-man.
"He's capable of doing those things, that's why he's in there working," Shell said. "His versatility is very important to what we're planning on doing on defense."
A strong first day, followed by a sluggish second day, ending on a high note on Day 3.
"I told them, `we're going to throw a lot of things at you, and you've just got to try and decipher and learn it the best you can,'" Shell said. "In the morning, you'd call a play, and their eyes would be as big as balloons, which should be expected. By the afternoon, you could see improvement. I think they're doing OK."
With John Madden being inducted to the Hall of Fame, the Raiders were selected to play the Eagles on Aug. 6 in the Hall of Fame game, with Madden at the microphone in his debut with NBC.
That gives Shell four more quarters to get a new staff and offensive system ready for the season opener Sept. 11 against San Diego.
"I've always liked the fifth game," Shell said. Some people don't like it, but I've always liked it because I feel it gives you a head start. That's going to be invaluable for us, especially with a new staff coming in on the offensive side of the ball."
"Aaron is a competitor and he's got a strong arm," Sims said. "It will be exciting to have someone in there that's got some mobility and some leadership. We're excited to have him here."
"I had to change," Francis said. "There weren't any plays in No. 10."
Francis, a former world class sprinter out of Texas Tech, suffered a knee injury as a rookie and had his training camp derailed by a hamstring pull last season.
