Darren McFadden, who has missed 23 games through his first five seasons, is eager for the 2013 season because of the new offense the Oakland Raiders will feature.

The team is going back to a straight-ahead power running scheme with new offensive coordinator Greg Olson and offensive line coach Tony Sparano.

McFadden's "most effective years have been in a downhill, power scheme," head coach Dennis Allen said. "That's why Greg Olson and Tony Sparano are here."

"This is very exciting for me," McFadden said. "I am the type of guy who likes to go downhill, make a cut and go; that's my thing. We'll mix it up like we used to, and get some zones in there, but for the most part, I will be keeping my shoulders toward the line of scrimmage."
