Thomas Jones put up 19 fantasy points in week 1, a feat he won't likely repeat. If you can get something decent for him, do it now while your opponents just see that 19. It was pretty much all garbage points. He ran terrible most of the game and just put up points near the end.
If it's possible, get anything, and I mean anything for Willie Parker or Mendenhall. They looked bad. Tim Hightower bad. Mendenhall is probably well recognized as worthless but you could fool someone into taking Parker.
If you can get something for Julius Jones, by all means do it. He didn't look bad, but he is not going to face the Rams every week.(just once more) The Rams look like they're going to be terrible; send everyone you can against them every week.
