RB help fantasy week 11?

I have steve slaton and willie parker.....i am leaning towards parker because he is ready to go against a very weak SD defense......and steve slaton has a pretty good matchup against the colts but here is where im concerned.....parker is coming back and might lose some carries to moore....and slaton might lose some carries to green because of the difficult week last week.....could i get some insight? i started thomas jones last night and he got me 17 points......i just need some input
