Which RBs to avoid? WHIR

[Willie P]

My draft is in 1 week, and I'm wondering out of the following RBs, which should I avoid? Which should I grab? and which are you indifferent on...basically put them into 3 tiers in order. I would appreciate this so much
Using PPR Scoring
Maurice Jones-Drew- How early do I draft him if he doesn't sign by the time I draft?
DeMarco Murray- The cowboys O-line looks awful and Felix could be of concern
Jamaal Charles-Injury concerns and Hillis taking away carries/tds from him
Trent Richardson- Injured, not sure if he will play week 1, team is bad, and he is only a rookie...
Steven Jackson- No question marks here, that I know.
Adrian Peterson- Coming back from an injury, history shows RBs coming back from his injury have a bust year.
Marshawn Lynch- May be suspended, but I really like him.

Not sure what you mean by putting them in three tiers by order but here is my take on them.
Charles-he is my favorite running based on value this season. I would not worry about touches because he has a career average of 6.1 yards per carry. Also he does not rely on touchdowns with 4 in 2010. I think he is fully healthy because he had a long time to recover unlike AP.
T-Rich-may not see 300 touches but will be a nice pick in the second round
Lynch-do not think he will get suspended this season, he will get the touches but may lack motivation after his big contract
Murray-he is a injury risk but has the talent to be a solid running back with the amount of touches he will see. I would like him as a RB2
Steven Jackson-age is a concern but he will put up a top 15 season again
AP-still going to high, I think he will be full go by mid season though
MJD-one of the most used running backs over the last three seasons and the holdout has put him on my do not draft list.
