NFL free agency has started, which means we have old faces in new places (or old places in some cases). Here's a look at some of the biggest moves involving running backs this offseason and how it impacts fantasy football for 2014.

Toby Gerhart - Jaguars: Maurice Jones-Drew was already on his way out of Jacksonville and Gerhart's signing was just the door closing. Gerhart enters a situation with little competition, which means he will likely be given a chance at the starting job.

In fantasy, not everything is about talent. Opportunity is huge. So while Gerhart may not be the most talented running back available, he's an attractive option simply because he'll get a lot of touches.

We saw some of what Gerhart could do last season. He had two games with over 80 yards rushing and was able to average 7.9 yards a carry as the backup to Adrian Peterson. That number won't stand, but it's encouraging to see him produce at a high level. He has RB2 potential in Jacksonville.

Ahmad Bradshaw - Colts: Ahmad Bradshaw re-signed with the Indianapolis Colts early this offseason. He adds his name to a crowded backfield that includes Trent Richardson and Vick Ballard.

All three players have question marks. Bradshaw and Ballard are recovering from season-ending injuries and Richardson is recovering from a terrible season. I'm tempted to stay away from the Colts backfield entirely when it comes to draft day. This will likely be a RBBC (running back by committee) which means these guys will each diminish one another.

Rashad Jennings - Giants: Andre Brown may not be back and David Wilson is recovering from offseason neck surgery. Enter Rashad Jennings.

Jennings showed promise as a member of the Jacksonville Jaguars during his first three years in the league. Last season he got a chance to start for Oakland following some injuries and he impressed. During a six game stretch Jennings rushed for about 90 yards a game and scored six times.

Jennings has a chance for the starting role in New York which makes him a valuable option. If he can keep the starting job he has RB2 potential.

Ben Tate - Cleveland: Cleveland needs an every down rusher and they got one with Ben Tate.

Tate missed his entire rookie year with an injury. In his first season with playing action (2011) the Texans' running back nearly rushed for 1,000 yards (942) backing up Arian Foster. In 2013 Tate started seven games following an injury to Foster, but he dealt with injuries himself.

The Texans back rushed for 771 yards on 4.3 yards per carry. It wasn't too impressive, but he was playing with broken ribs. He's now expected to be the lead back for Cleveland where he should find some success. Tate is talented and he has opportunity. There's RB1 potential for him in 2014.

Darren McFadden - re-signs with Oakland: It's a little surprising McFadden decided to stay in Oakland. A change of scene could have done him some good. As is always the case with Run DMC, he has the potential to be great, but carries a lot of risk. He's often injured and he often lets owners down. He should be viewed as a RB3 or RB4.

Joique Bell re-signs with Detroit: Joique Bell had 1,197 rushing and receiving yards last season with the Lions. His three-year deal proves Detroit likes what they have. Bell will be an excellent flex option this season, especially in PPR formats.

Darren Sproles traded to Philadelphia: Darren Sproles joins one of the most innovative offenses in the league. He should continue his success as a pass-catcher out of the backfield. I also don't see him taking value off of LeSean McCoy. Sproles is most valuable in PPR formats.

Donald Brown - Chargers: This move was a head scratcher. Why join a team where you're instantly third in line for touches? Ryan Mathews is coming off of his best season as a pro and Danny Woodhead had over 1,000 rushing and receiving yards last season. Brown will be the forgotten man and shouldn't be looked at in fantasy drafts this year.
