For now, I'll just breakdown the AFC East and AFC North, but will continue to update this thread when I have time- getting tired right now...
Buffalo Bills: McGahee is the starter, but is only making 905K next year (free agent in 2008). I wonder if he'll holdout for a better deal? As for the back-up, A-Train is on a one year deal. He seems to have produced, but will be 30 next year. I don't think they'll re-sign him. I imagine they will be drafting their back-up RB. It may be a high pick if they do not agree to an extension with Willis before that time.
Ronnie will be the starter. Although this may be a full blown RBBC if Ricky returns in 2007 which he is likely to do. If not, the fish will likely pursue a back-up in the off-season. Minor and Morris are both on 1 year deals. It is possible that Patrick Cobbs will be promoted to be the 3rd string guy if he can hold onto the ball. He led the Patriots in rushing in the preason and looked to have some playmaking ability. We'll know what they think of them if they sign him off the practice squad next week.
New England Patriots:
I am not sure of the exact nature of the 5 year $25 Mil dollar deal Dillon signed before the 05 season. You would think he would be asked to take a paycut or be released. If he takes a paycut, I can see Maroney taking over as the feature guy with Dillon handling the goalline carries. Kevin Faulk's contract doesn't expire until 2010, but you have to wonder if the Patriots are going to pay him 1.9 mil in 2007 (increasing $500k each year after that). FWIW, Pass and Evans are both free agents in 2007. It all depends, but it's possible New England will have a new back-up RB in 2007.
New York Jets:
What a mess. Washington, Barlow, Houston, and Blaylock all have contracts beyond 2007. Washington has looked better than expected. Barlow and Houston have been inconsistent. Blaylock doesn't look the same as he did running behind KC O-line and after suffering a foot injury in 2005. If the right draft pick falls to them (Adrian Peterson anyone), I can see them pursuing that route. Although if the right player doesn't fall in their lap, they do seem to have some decent depth and many other weaknesses on the team to address. I think they could stick w/ the status quo with these guys producing in a RBBC. It should be noted that releasing Barlow will not affect their cap situation, so I think they may audition Cedric Houston down the stretch to see if he is capable of taking care of the short yardage/complement to Leon role. If Kellen Clemens can grasp the offense and beat out Pennington along with an improving relatively young o-line, these guys might be able to produce. Lets remember, Mangini comes from the Belichek plug and play school of thought and was around when they won a super bowl w/ Antowain Smith at RB.
The Ravens have a $5 Mil option on Jamal in 2007. It's hard to say whether they will re-sign him or not. He has produced fairly well since Billick took over play calling duties despite missing Mulitalo at guard and overall poor o-line play. Mike Anderson signed a back-up players contract, and will likely return since he is a quality team player. Musa Smith is a FA and I expect him to be somewhere else next year with PJ Daniels taking over as the 3rd down/COP guy. Cory Ross is also an interesting prospect, he made the 53 man roster, but I don't think he has been active yet...
1) Rudi 2) Perry. Watson is a FA in 2007. Quincy Wilson led the NFL in rushing in the preseason, but is currently on the practice squad. If Watson leaves, I would expect Quincy to be the 3rd string guy in 2007 although they will likely bring in some competition either via a thrifty FA signing or thru the late rounds of the draft. I am surprised another team hasn't claimed Wilson yet...he could be an outstanding goalline back. I thought he was impressive while at West Virginia.
I would expect Rueben Droughns to remain the starter. He just got an extension before the season. Jerome Harrison, however, will likely have an expanded role. I can't seem to find the contract status to Jason Wright. I would expect him to return and factor into the mix if something were to happen to Rueben. Although, keep an eye out for the FB/RB tweener Lawrence Vickers, the 6th round pick could be a solid short yardage back. I would expect the Browns to bring in another mid-round pick to challenge this group of mediocre RB's.
Willie Parker is a great story, he's the feature back for the near future and has shown a nose for the goalline despite his small stature. He also has held up fairly well thus far in 2006 while carrying the load. Najeh Davenport has done a decent job thus far, but he's on a 1 year contract. I would expect John Kuhn, another tweener FB/RB who was impressive in the preseason, to challenge for the short yardage role. It's hard to figure out why Duce Staley is making 2.5 mil this year to be inactive- I would expect him to be gone next year. Pitt will pursue a RB that will challenge for the back-up job in the draft or via free agency. I don't expect Cedric Humes to ever have an impact...
