ALAMEDA -- The Raiders defense was just shredded by a 29-year-old rookie in Brandon Weeden for a career-high 364 yards through the air.So on a short week, how in all that is holy in Silver and Blackdom do the Raiders prepare for a rejuvenated Peyton Manning, who rides into town with his Denver Broncos for a primetime game Thursday?"Well, youre never really ready for Peyton Manning," admitted Raiders defensive coordinator Jason Tarver. "Its a matter of getting on the same page and having enough coverage looks to hopefully slow down his progression, and challenging guys in coverage. Thats what we need to do."Easier said than done, right?Especially since the Broncos, at 9-3, have already clinched the AFC West and Manning is the seeming front-runner to win both the league MVP and Comeback Player of the Year awards.Plus, Manning already smoked Oakland earlier this season, throwing for 338 yards and three touchdowns without an interception on 30 of 38 passing in Denver's 37-6 blowout win on Sept. 30. Manning's passer rating that day was 130.0.But the Raiders were within 10-6 at halftime that day."In the first game, we had a lot of times where he threw into coverage and we need to make those plays," Tarver said. "We need to make those plays. And that was kind of the difference in the game was they made more plays than us on those type coverages. We have enough in our system to hopefully put guys in position to make plays and that ultimately is the job of the coaching staff -- put players in position to make plays."Another obstacle for the Raiders is that the Raiders lost three players in their secondary to concussions Sunday in safeties Matt Giordano and Mike Mitchell and cornerbackpunt returner Phillip Adams and the protocol for returning from a head injury can be lengthy.So how, again, do the Raiders stay focused against Manning?You just play for pride, said free safety-turned-cornerback Michael Huff. We dont want to go out there and get embarrassed Thursday night. Our family, friends, high school coaches, little league coaches, everybody will be watching us. If you dont want to not get embarrassed you shouldnt be playing this game. For me, playing for pride."
