There can be nothing more frustrating for a fantasy football player than teams who use running backs by committee. However, these players can still be effective on your roster, which Jacksonville has proven over the last few years. Here is a look at how some tandems will play out this season.

Willie Parker and Rashard Mendenhall, Pittsburgh Steelers: This is an interesting one because you have an established runner with a first-round pick, and it just so happens that the established player is coming off an injury and scored all of two rushing TD's last season. But earlier in training camp, Steelers coach Mike Tomlin made the declaration that Willie Parker would get the goal line carries, greatly increasing his value. Mendenhall will still get his share of carries, but feel safe using Parker as a No. 2 back.

Adrian Peterson and Chester Taylor, Minnesota Vikings: This isn't necessarily a RBBC, but more of an understanding that Peterson will be the man, with Taylor still getting his. Taylor's value comes because of Peterson's injury history, which is lengthy. When both are healthy, Taylor is clearly the second back, but he is still draftable because at any point he could become the starter again.

Maurice Jones-Drew and Fred Taylor, Jacksonville Jaguars: Fred Taylor is now 32 years old, well past the age when most running backs begin to break down. That will come at some point, and maybe even this season. Jones-Drew is the guy who will be getting into the end zone, and his value has increased a little each season.

Marion Barber and Felix Jones, Dallas Cowboys: Barber is going to be the workhorse back here, even though Dallas spent a first-round pick on Jones. Barber will get the tough yards and will certainly be the goal line back, with Jones getting most of his work between the twenties.

Ronnie Brown and Ricky Williams: Because of the horribleness of the Dolphins last season, you don't hear much about this duo. But Brown, a former No. 2 overall pick, was on his way to a career year before injuring his knee in '07. And Williams is said to be working hard and in shape, ready to go. It's unknown how the carries will be split, but don't be surprised if both wind up being solid fantasy options.

Darren McFadden and Justin Fargas, Oakland Raiders: Expect this one to go down a lot like last year with Peterson and Taylor. Both will get their share in the beginning, but McFadden will wind up being the man towards the end of the season. Every report out of Raiders camp has glowed about DMC, so his status in fantasy leagues is moving up rapidly.

DeAngelo Williams and Jonathan Stewart, Carolina Panthers: Most people are writing off Williams and proclaiming that Stewart will be the man, but that's not necessarily the case. Stewart is still recovering from his injured toe, and he is not yet 100%. Williams very well could see the bulk of the carries early in the year, with Stewart playing a more prominent role later on. But it would be a mistake to overlook the amount of carries Williams, a former first-round selection, will receive.
