A couple backs went down in Week 4. Alfred Morris was extremely durable during his rookie season in 2012, but he suffered a rib injury. On the other hand, the oft-injured Darren McFadden shocked nobody with a hamstring strain. Both players could miss time, so their backups become top targets off the waiver wire.
Danny Woodhead (owned in 41 percent of leagues)
He's a bit of an obvious pickup, especially in PPR leagues. He's on pace to catch 80 balls and the Chargers are lining him up all over the field. Clearly, he's part of the solution as receivers for while Malcom Floyd is on the mend.
Rashad Jennings (owned in 5 percent of leagues)
As mentioned in the intro, Darren McFadden could miss some time with a hamstring injury. Based on his past, it's likely that he could miss more than one week. What's more, Marcel Reece also went down and could miss some games.
The Raiders are very thin behind those two, and it looks to be Jennings' show. He ran the ball 15 times for 45 yards against the Skins while Taiwan Jones was the only other tailback to get a carry after DMC went down.
Jennings hasn't been the same since his ACL tear back in 2011, but he's shown some skills and burst. He should be able to flirt with 20 touches, which will give him value in most formats. He's a nice bye-week option against the Chargers in Week 5.
Roy Helu Jr. (owned in 12 percent of leagues)
Rib injuries are never fun for running backs. They take too many hits and all of them are now going to hurt a little more for Alfred Morris. The good news is that Morris didn't suffer any structural damage. Helu has already proved himself as the top backup and he had one of the better preseasons of any running backs.
It's also worth nothing that he has a 14-catch game on his resume, so he could be a very nice option in PPR leagues. The Skins are on a bye, so Helu is just a handcuff since it's unlikely that Morris misses time.
Willis McGahee (owned in 46 percent of leagues)
Just like everyone thought, the Browns are tied for first place and it's been because of Brian Hoyer. They have been able to effectively move the ball through the air while their ground game has been non-existent.
Their opponents will have some tape on Hoyer and things should eventually open up on the ground. Willis is the only back that is capable of running between the tackles on a consistent basis. Don't dismiss his 46 yards on 15 carries from Week 4. He's a strong own, but isn't worth starting in most situations since he gets the short week, but the Bills haven't been very success in stopping teams all year.
Andre Ellington (owned in 11 percent of leagues)
Rashard Mendenhall continues to get carries and he continues to not do much with them. He led the team with 12 totes on Sunday, yielding only 21 yards. Ellington on the other hand needed just four carries to account for 29 yards. He's up to 6.2 yards per carry on the season and he's been effective in the passing game. The rookie saw six targets against the Bucs, catching three of them during a win.
The Cardinals still haven't worked out their kinks in the new Bruce Arians offense, but they should have it figured out in due time. They get the Panthers in Week 6 and it might be time for the team to get Ellington more work.
LeGarrette Blount (owned in 5 percent of leagues)
He's back. Blount was in the fantasy doghouse after fumbling too much and dancing too much in the backfield while with Tampa Bay. Blount ripped off a 47-yard run, finishing with 64 yards against the Falcons. The Patriots have a straight split at running back with Stevan Ridley and Brandon Bolden also getting carries.
It's really a mess, but considering the way the Patriots can score a bunch of points, so there's some upside with the Blount Object. He's a speculative scoop in case the Patriots ever decide to stop playing with fantasy owners' minds. Also, owners might want to think about picking up Shane Vereen.
Chris Polk (owned in 0 percent of leagues)
The Eagles run the ball a little bit and Polk was able to play the role of vulture with a TD. He's the third back on the depth chart, but the Eagles have such a formidable rushing attack that he would be a decent flex guy should either LeSean McCoy or Bryce Brown go down.
Benny Cunningham (owned in 0 percent of leagues)
The Rams are having some issues at running back. Isaiah Pead was a healthy scratch in Week 4, which came to be a bit of a shock after he was solid in Week 3. Daryl Richardson is also unable to stay on the field.
He had just six yards on four carries, so it's not like he's earning the role. This is a speculative add in deep leagues.
Ronnie Hillman (owned in 23 percent of leagues)
The Broncos blow out so many teams that Hillman has value. They will continue to do so and Hillman will get more garbage time stats throughout the season. They might play a somewhat close game in Dallas, but they get Jacksonville in Week 6.
Hillman does get some work on third down and he accounted for 20 carries over the past two weeks. He's almost unplayable in standard leagues, though.
Chris Ogbonnaya (owned in 3 percent of leagues)
Silent G caught five balls and ran it five times for a total of 48 yards and a score. The Browns are going to ramp up Willis McGahee's work load. Consequently, he is more susceptible to injury. The Browns are actually moving the ball, so there's some upside should Willis miss games.
