Any draft is a success when the Raiders come away with a DeMarcus instead of a JaMarcus.

Or when they add a second-generation Wisniewski to their inner circle.

Or when they don't have to gamble a high draft pick on a skill-position phenom, kickers included.

Idle for Thursday's first round, the Raiders rationally stocked up on offensive linemen and cornerbacks Friday before finishing Saturday's rounds with four consecutive offensive reinforcements.

Defensive depth is a concern, but if the Raiders were willing to largely ignore that the past few days, you can wait a few paragraphs before analyzing it.

Overall, it was an acceptable haul, and first-year coach Hue Jackson cooed once the Raiders filled out their eight-man draft class.

"This organization, this team is going to become something," Jackson said. "I can't tell you how fast it's going to happen. But I know that it's going to happen."

He can speak confidently because the Raiders entered this draft with their offensive playmakers already in place, led by running back Darren McFadden, their 2008 top draft pick.

New offensive tackle Joe Barksdale is familiar with McFadden. Barksdale, a third-round pick Friday, was a freshman at LSU in 2007 when McFadden led Arkansas to a triple-overtime win over the top-ranked Tigers.

"He played against us his senior year, and I remember him beating us single-handedly," Barksdale said Saturday. "It'll be exciting to block for running backs like Darren McFadden and put points on the board."

Adding live bodies to the offensive line was a must in this draft, and that started with the selection of center Stefen Wisniewski (nephew of former Raiders guard Steve Wisniewski) with their first pick, the 16th selection in Friday's second round.

Instantly, Wisniewski was pegged the starting center. It's a titanic task for any rookie. But he looks capable thanks to his Penn State experience and his uncle's mentoring.

Cornerback is the only defensive position the Raiders addressed, taking Miami's DeMarcus Van Dyke in the third round and Ohio State's Chimdi Chekwa in the fourth. Smart move adding that tandem to a cornerback corps that likely is subtracting Nnamdi Asomugha in free agency, whenever that begins and the labor lockout ends.

Wasn't it just last year that the Raiders drafted two cornerbacks? Yes: Walter McFadden (fifth round) and Jeremy Ware (seventh). The more the merrier to help veterans Stanford Routt and Chris Johnson.

Written on the back of Chekwa's draft card -- according to a photo on the Raiders' website -- was this message from a legendary Raiders cornerback: "Your work is cut out for you! Be the best. -- Willie Brown, HOF 84."

The Raiders had the second-best pass defense in terms of yards allowed last season. However, their run defense ranked 29th, and this draft did nothing to help that cause.

"On our defensive football team, I expect us to be one of the best defenses in football," Jackson said. "And I'm not just saying that. I believe that. We have some tremendous, tremendous players over there."

They've made tremendous financial investments over there, too, with Routt, middle linebacker Rolando McClain (last year's first-round draft pick) and defensive linemen Richard Seymour and Tommy Kelly, whom teammates voted as their 2010 defensive MVP.

It's not that the Raiders have holes in their starting defense -- safety Michael Huff might flee as a free agent -- but their depth should be a concern for new coordinator Chuck Bresnahan.

As for quarterback, the Raiders did not select one in this draft. Vince Young or another veteran castoff should be brought in to challenge incumbent starter Jason Campbell and lone backup Kyle Boller. That is a potential move on indefinite hold, courtesy of the lockout.

Asked if Campbell or any teammates has communicated with him yet, Wisniewski said: "I haven't talked to anybody yet. I'm sure it will happen."

It had better, if the Raiders want their newcomers to blend in quickly to a franchise that's opened a long-lost window to success. While those vets are at it, sneak all rookies a playbook.

As for the raw receiving corps, it needs a veteran, such as the Panthers' Steve Smith or Bengals' Chad Ochocinco and Terrell Owens. This draft brought two new targets: Tennessee's Denarius Moore (fifth round) and USC's David Ausberry (seventh round).

If Asomugha leaves, the Raiders locker room will need a new unofficial spokesman, in good times and bad. Seymour and Campbell spoke up enough last season for one to think they could do more of that, and their veteran presence will key the leadership drive.

This just in: They have a team worth leading, something rarely said after a Raiders draft this past decade.
