Mike Williams (sea)
Deon Buttler (SEA)
Chris Ivory (NO)
Starks (GB) This would be a huge reach right now.
Mike Williams is a nice add, I think he will continue to get targets and should continue to be an okay fantasy option. I'm not so high on Butler, as it seems the coaching staff wants Williams to be the #1. Meachem is okay, I dont really like any Saints WR as they spread the ball around so much. Avant might be a good bye week or injury filler for a few weeks, Kolb tends to like the mid range passes which are the routes Avant runs. Burleson also looks good, although on a bye week, with teams giving Calvin safety help, he should continue to see easier coverages. Dont like Armstrong, Moss seems to be the better option there along with Cooley.
So, I would probably go Burleson or Williams for the long term, Avant if you need a bye week or injury filler. Burleson and Williams are probably better options then Tate, just because he's taking over Moss' roll doesnt make him Moss.
I dont like Chris Ivory, espeically with it looking like Pierre Thomas might be coming back this week, although with him being so injury prone he is a good add to stash on the bench incase of another injury to Thomas. Caddilac has been getting the bulk of the carries, but he doesnt do much with them, so I'd probably stay way from him. Forsett is interesting, I think he's got much more big play potential then any other RB Seattle has, but Seattle seems to like Lynch. Ward looks like the backup to Foster, but Foster is still getting the majority of the carries. If Foster even looked like he might get injured I'd pick him up, but not until then. Starks is a huge reach, and you could probably hold off for a few weeks on him.
Only RB i'd pick up would be Ivory, and that would be more of a stash and see type pick up, unless Thomas doesnt come back, then he's a must pick up. Buffalo seems content with giving Spiller 10-15 carries until he can prove that he can take more.
