Raiders running back Darren McFadden might need a big year in 2013 if he wants to get paid, reports Joel Corry, a former sports agent who writes for CBSSports.com.

McFadden has been unable to reach his potential because he has been plagued by injuries during his five seasons in Oakland. He hasn't played 16 games in any season and has missed 23 games during his NFL career.

McFadden was ineffective last year in the zone blocking scheme implemented by offensive coordinator Greg Knapp, who was fired after the season. The power blocking scheme under new coordinator Greg Olson could help McFadden return to his 2010 form, when he rushed for 1,157 yards -- his only 1,000-yard rushing season -- and was sixth in the NFL with 1,664 yards from scrimmage.

The Raiders are expected to have more than $50 million of cap room in 2014, so they could carry McFadden's $11.586 million franchise tag number if necessary.
