I already posted some of my QB candidates to be busts this year. Here are a couple running backs who might disappoint fantasy owners:

Marion Barber (DAL) – Barber was one of the bigger disappoints last year, so I'm sure people are expecting less from him this year. However, I've seen some list him as a comeback player this season, but I frankly don't see it. Barber has lost his starting job to Felix Jones and loses goal line touches to Tashard Choice. He only had 700 yards last year, I expect even less thant that this year. Barber is no better than a RB3 at this point.

Rashard Mendenhall (PIT) – This isn't just my anti-Steeler bias showing here. Many experts think Mendenhall will be a solid RB1 option this year and I'm not sold. Don't get me wrong, Mendenhall is a young talent, but I think the Steelers have done nothing to improve their offense this offseason, and in fact, have gotten worse. No Big Ben for 4-6 games, no Willie Parker to spell Mendenhall, and no Willie Colon at right tackle. The Steelers offensive line was sub-par last year and they look older and worse this year, especially with Colon out for the year. I think defenses will stuff the box for at least the first 4-6 games to stop Mendenhall, so I think a slow start is likely. Tamper expectations on Mendenhall and in my book, he's more of a RB2 guy and not an elite running back, at this point.

Jamaal Charles (KC) – Charles, like Mendenhall, started 2010 as an early favorite to be a breakout player. But then a couple things happened to diminish his value some. The Chiefs signed Thomas Jones, the Rodney Dangerfield of the NFL. Jones, who is written off every year and gets no respect, will hurt Charles' value. Also, the Chiefs drafted Dexter McCluster who will be a hybrid RB/WR/Wildcat player who will take some of Charles' catches out of the backfield. And there is the very shaky Chiefs offensive line. All of this drops Charles from RB1, top 20 selection to an RB2-type of player who should be taken in the late third round.

Steve Slaton (HOU) – Much like Barber, Slaton was one of a handful of running backs to bust the hopes and dreams of fantasy owners last year. Which means he's due for a comeback, right? No way. The Texans drafted Ben Tate to take over in the backfield. Slaton didn't help his cause either with 7 fumbles. So now Tate takes over and Slaton moves to the sidelines. In PPR leagues, Slaton will carry a little more value, but at best he's a low-end RB3 or bye-week replacement.
