Is it time to give up on Hillis?

Only 3 weeks, but hasn't done crap, Draughn talking some of his carries, and now injured.

12 team league, non ppr, all TDs 6 pts, otherwise standard scoring. Start 2 RBs, no flex. Limit of 4 RBs on roster. Other 3 RBs are foster, McFadden, and Tate. With the 4 rb limit, there are some pretty good options available on waivers. My top target would be Fred Jackson, which seems like a no brainer. Ryan Williams also available.

I've pretty much made up my mind, but I've dropped players too early in the past, so figured I'd get other opinions.

Thanks
