About one-third of the NFL uses a significant form of a running back committee right now. Throughout the season, different backs will be weighted differently within these committees.

Analyzing the weekly carry fluctuations will help us stay on top of what’s going on at the most important position in fantasy football.

Here’s a look at how the carries were distributed in five of the more interesting running back situations around the league, with a take on what it meant.

For a complete running back report, plus all the tools you need for Week 2, check out the Season Pass.

COLTS
Joseph Addai: 17
Donald Brown: 11

Addai was in for the opening series and got Colts’ the first five carries of the game. In the first half, Addai had 12 carries while Brown had two. But the second half was all Brown. In the fourth quarter of a close game, Addai got two carries while Brown got six. Addai is clearly on a short leash.

The bottom line is that the Colts’ running game is in really bad shape. In 2008, they were dead last in the NFL at 3.4 yards per carry. On Sunday, Addai and Brown averaged a combined 2.68 yards per carry. The offensive line is not opening holes and this committee is looking like a fantasy wasteland right now.

PANTHERS
DeAngelo Williams: 14
Jonathan Stewart: 11
Mike Goodson: 2

There is an asterisk next to this one because the game was over in the second quarter. The biggest thing we can take away is that Stewart is healthy and the Panthers will use him at the goal-line. On the very first drive of the game, Stewart got the call three straight times from the three-yard line and in.

RAIDERS
Darren McFadden: 17
Michael Bush: 12

This committee gets a twist for Week 2 as Justin Fargas, who was inactive on Monday night because of a hamstring injury, is expected back.

Here’s Tom Cable on his running backs, per beat writer Jerry McDonald:

“I look at it as Darren is the starter, and the other two guys are his backup,” Cable said.

Here’s more Cable on using three backs:

“We’re going to have two primary runners in every game. You’ve got to have your third ready to go. … Justin is proven and proven in this system. What it does is bring a couple more packages into the offense, so hopefully we’ll get to do some of that this week.”

Still, don’t expect Fargas to get very many touches. Bush is a much better running back. McFadden will be the workhorse, with Bush taking over in the red-zone.

RAVENS
Ray Rice: 19
Willis McGahee: 10
LeRon McClain: 6

Rice got six carries before McGahee or McClain got any. The Rutgers product is the clear starter and featured back as he got all but one of the Ravens’ first-half carries. McGahee is the goal-line back, but it’s worth noting Rice got the call on a second-down from the five-yard line in the second quarter.

The Ravens spread the ball around more in the second half, but 19 carries per week is looking like a lock for Rice right now.

BRONCOS
Knowshon Moreno: 8
Correll Buckhalter: 8
LaMont Jordan: 2
Peyton Hillis: 1

Buckhalter started and had his number called on three straight plays to open the game. The second series went to the rookie Moreno. From there, the Broncos basically abandoned the run. Jordan and Hillis got spot-duty, further draining any value out of Moreno or Buchalter.

It’s not like Moreno was impressive anyway. He averaged 2.4 yards per carry and blew a blitz pickup. This situation is feeling very Patriots-esque.

COMMITTEE REPORT QUICK HITTERS
Two of the names that aren’t in any type of committee are pretty interesting: Kevin Smith and Cedric Benson. The rest are the big-boys: Matt Forte, Maurice Jones-Drew, Frank Gore, Michael Turner, Steven Jackson. … Laurence Maroney led the Patriots in carries with 10. … Brandon Jacobs had 16 carries while Ahmad Bradshaw had 12. … Beanie Wells had just seven carries, but that number should steadily rise as we move on. … Leon Washington led all “No. 2” backs with 15 carries.
