Another slow offseason day calls for another edition of the NFC East position series -- our position-by-position look at each of the teams in our division. There's no pre-planned order to any of these, so it means little that I've chosen to look at running backs today and to start with the Dallas Cowboys.

Projected starters: RB DeMarco Murray, FB Lawrence Vickers

Reserves: RB Felix Jones, RB Phillip Tanner, RB Lance Dunbar, RB Darrell Scott, FB Shaun Chapas

Potential strength: Murray performed like an elite-level workhorse in the seven games he played as a starter before the Giants game in which he broke his ankle. He averaged 114.1 yards per game and 5.96 yards per carry during that seven-game stretch. And Jones, the fifth-year former starter, had two 100-yard games after Murray went down. So they have a high-level starter and an experienced, capable backup, and they believe Vickers will play even better than Tony Fiammetta did for them as the lead blocker last season. And Tanner is a good third running back who's shown encouraging flashes and should stick around due to his contributions on special teams. Assuming everyone's healthy, this is a unit capable of big things.

Potential weakness: Even while he was rolling up all of those yards, Murray scored just two touchdowns last year. And Jones only scored one. The Cowboys had just five rushing touchdowns as a team in 2011. Only the Cleveland Browns scored fewer. As good as Tony Romo, Dez Bryant, Miles Austin and Jason Witten can be in the red zone, it would help if the running backs posed more of a realistic threat to score at the goal line. Red-zone production is an area in which the Cowboys' running game must be better than it was last year.

Keep an eye on: The on-field relationship between Murray and Vickers. Murray and Fiammetta made a very productive team last year. The Cowboys believe that had more to do with Murray than it did with the fullback, and they think they've upgraded at fullback. But Murray had an innate sense of where Fiammetta was going to go and what would result in terms of opportunity for him thereafter. Murray said during minicamp that he's getting to know Vickers, and it's unlikely to be a problem. But that chemistry he had with the fullback last year was part of his success, so it's at least worth watching to make sure he finds something similar with the new guy.
