Chris Wesseling of Rotoworld ranks the RB position in dynasty format. Here are his top two tiers:

Tier One

1. Adrian Peterson, Vikings
2. Chris Johnson, Titans
3. Jamaal Charles, Chiefs

The three most uniquely talented backs in the NFL. All three of them can produce RB1 fantasy numbers regardless of coaches, scheme, or even supporting cast. CJ2K is a fantastic buy this offseason. … Charles proved to be the best player on the field against the Ravens in the Wild Card round loss. That comes as no surprise to anybody who has watched him play on a regular basis the past two seasons.

Tier Two

4. Arian Foster, Texans
5. Ray Rice, Ravens
6. Maurice Jones-Drew, Jaguars
7. Jonathan Stewart, Panthers
8. LeSean McCoy, Eagles
9. Rashard Mendenhall, Steelers
10. Darren McFadden, Raiders

Foster emerged as one of the premier all-around tailback talents in the league. Though his success is not merely a byproduct of Houston’s zone-blocking scheme, there’s no question that he’s ideally suited to Gary Kubiak’s offense. … Like Chris Johnson, Rice is an outstanding buy this offseason. Despite a dramatic dropoff in run blocking (and a heavy dose of bad luck), Rice still finished third in the league in total yards. The touchdowns are coming.

Jones-Drew belongs in the top tier on talent alone, but the knee is cause for pause. Meniscus surgery isn’t automatic. Just ask Antonio Bryant and Torry Holt. … Stewart is one of the handful of most talented backs in the NFL, and we’ll see that on a regular basis if the Panthers move on from free agent DeAngelo Williams. … McCoy benefits from playing with Michael Vick. He also proved more than capable of filling the Brian Westbrook role. … Mendenhall doesn’t wow onlookers, but he does everything well as the workhorse for one of the league’s steadiest franchises. … McFadden would be at least three spots higher if we could count on him to play 16 games a year.

I’d probably have the same Top 10, though I think I’d have McCoy ahead of MJD and Stewart. That may be because I play in mostly PPR leagues and his value is enhanced in that format. We’re equally high on Jonathan Stewart, assuming DeAngelo Williams moves on. Ron Rivera is a great defensive mind, and that generally lends itself to a run-oriented, ball control offense.
