Which 2 RBS? MoJo, Hillis, Williams

[reallyred]

I've got:

Maurice Jones-Drew (JAC) @ Colts
Peyton Hillis (CLE) @ Cin
DeAngelo Williams (CAR) @ NO
Willis McGee (BAL) @ PIT

I can play two.
Jones-Drew has been disappointing, but I'll probably play him. I really don't see any upside to McGee, so my choice is basically down to Hillis or Williams?

Thanks! If you post a link to your question I'll comment back, but this is my first years so you can take my advice for what it's worth (not that much).
