The rookie to break out this season will be the Oakland Raiders' Darren McFadden.
He has killer speed and killer moves by high stepping and juking out the defense. You might be saying he does not have a good offensive line. Al Davis made one bad draft choice a couple years back by drafting Robert Gallery.
He was a bust, but in this year's draft McFadden fell into Davis' hands like Peterson fell into the Vikings hands. McFadden will want to go all out and win Rookie of the Year because he feels he has been overshadowed by finishing as a runner-up for the Heisman Trophy.
He has JaMarcus Russell as his QB, so with Russell's running ability they could run the option play. When McFadden dominates this season in the NFL, it will not be for his offensive skills, but for his pure athletic ability.
The only way McFadden will not dominate is if he has to split carries with Justin Fargas. McFadden also lined up at QB and WR during minicamps, so stay tuned; he could line up pretty much any where on the field.
So this season, stay tuned when McFadden carries the Raiders.
