SAN DIEGO -- Chargers wide receiver Craig Davis absorbed his NFL moment this week. It came when the team announced Tuesday that Miami's Chris Chambers was acquired in a trade.

Davis, a first-round pick in April, will feel the brunt of Chambers' arrival.

While Vincent Jackson's spot in the starting lineup remains, Davis gets bumped by Chambers, a seven-year pro.

"I'm OK with that," Davis said on Thursday.

Davis said it without crossing his fingers.

"Chris is a Pro Bowl guy," Davis said. "And I'm a young guy who has no problem with looking up to an older guy -- whatever can help the team. I'm not selfish at all."

Good thing. Because the NFL, if anything, is one big revolving door. And if anyone not named LaDainian Tomlinson thinks his Chargers job is safe, think again.

"That's the business," safety Clinton Hart said. "But this organization did a great job bringing Chris in, and he is definitely going to help us win."

Chambers looks at his presence as a win-win.

"I tried to let Craig know that I'm not trying to be the man or the go-to guy," Chambers said. "I'm here to play, and help the team win and help him grow as a player. He is still a rookie; he is going to play and still get his opportunities."

Chambers was in Davis' cleats once. When getting his NFL baptism, he cooled his jets behind James McKnight and Oronde Gadsden.

"They took me under their wings," Chambers said. "I watched them prepare, take care of their bodies and learned from them. And it meant a lot to me, and I want to be that same kind of guy."

Davis seems eager to be a sponge to Chambers' knowledge. After absorbing his business lesson.

"This is the NFL, man," said Davis, who has nine catches for 84 yards and a touchdown. "I understand the organization wants to win, and I want to win. So we are in it all together."

While hoping the Chargers have added another piece to a championship puzzle, Hart speculates Chambers will motivate others.

"You definitely notice the difference," Hart said. "Everybody is coming out hurt; they are practicing.

"Before a guy with a little nick may not practice. Now he can't afford to sit out; he is going in there to play. You sit out, and take your time, and try to heal and all that stuff? If so, you will get left behind.

"He will definitely push these guys to get better.

Added Chambers: "I'm here for experience. I have a lot of experience playing this game. I think I have a lot to show these younger guys. I'm unselfish and I want to do whatever I can to make them better players."

Jackson is among those able to benefit from Chambers' background.

"I got a chance to sit down and talk with him a little bit," Jackson said. "He is a real solid guy, and I think he is going to fit in real well."

Chargers notes

Gotta be true to your school, and the Chargers were just that on Thursday, their last practice before enjoying their bye weekend. The players wore their college football jerseys save one -- TE Antonio Gates. He wore his Kent State basketball jersey. RB LaDainian Tomlinson looked good in his No. 5 Texas Christian jersey. "That was the something we had been planning for a while now," Tomlinson said. "It's good to see everybody in their old college jersey. It kind of gives you that feeling of going back to college days, just playing the game on Saturday afternoons, big crowds, and it takes you back a little bit and takes your mind off the media and big hype of the National Football League. It was all fun today." … Among Thursday's highlights were some individual races after practice. LT Marcus McNeill raced the length of the field against FB Lorenzo Neal, with McNeill getting a 10-yard head start. McNeill prevailed. "I think I'm going to race L.T. next time," the 6-foot-7, 336-pound McNeill said. "I picked up some nice change for the bye weekend." … The team resumes preparations for the Texans on Monday.
