With the 4th pick in the 2008 NFL Draft, the Oakland Raiders selected running back Darren McFadden from Arkansas. Al Davis does some of the most bizarre things these days, the most recent being when he overpaid defensive lineman Tommy Kelly, despite the fact that he was coming off of a serious injury. If McFadden is on the board at this point though, it should be a 99% lock that the Raiders will take the best running back in this year's class. This is the type of pick that absolutely turned around the Minnesota Vikings season last year compared to two years ago.
McFadden ran a 4.33 at the combine and would probably be able to beat out Justin Fargus for the starting role. McFadden can do everything that a running back can be asked to do -- run effectively, block consistently, and catch the ball regularly. That, paired with the potential of second-year quarterback JaMarcus Russell, would add the "big-name" publicity that the team has lacked since their Super Bowl run (and, their failed efforts with Randy Moss).
McFadden is an outstanding athlete with quick and agile feet. He has had some off-the-field issues with his character, and ball security remains a slight issue.
