Lineup thoughts

I usually don't ask for advice on here but figured I'd ask because I'm in a must-win situation in this league. My team has been highly unlucky this year as I've scored the most points but find myself only 4-6 because I've also had the most points scored against as well.

My team got off to a great start this week as I started Ricky Williams who got me 36 points.

Pick 1 RB

Steven Jackson vs Arizona
Rashard Mendenhall @ Kansas City

Pick 1 WR to go along with Colston(@TB) and Sidney Rice(Vs. Sea)

Calvin Johnson vs Cleveland
TJ Houshmanzadeh @ Minnesota

This is also a PPR. Right now I'm rolling with my two studs in Jackson and Johnson but can't ignore Mendenhall(juicy matchup) and TJ(been playing well lately).

Thanks for any advice.

I'd stick with S-Jax -- basically guaranteed 30 touches -- and Housh -- Vikings are surprisingly vulnerable through the air.
