Help rank my WR/RB (KR yardage counts)

[sirsydney]

(Kick return league = 1 pt/10 yds)
I have the following WRs to choose from:

* Harvin vs DET (should play)
* Collie @ DEN (if Bailey plays, he'll be on Wayne)
* Clayton vs WAS (#1 in STL)
* Cribbs @ BAL (gets KR & punts)
* Tate vs BUF (will Buffalo even kick off more than once?)

These are my RBs:

* S. Jackson - lock
* M. Turner - lock

* D. Sproles -@ Seattle (gets KR & passing, and with Matthew out)
* Tolbert @ SEA (will be the #1 this week)
* F. Jones @ HOU (eventually he might be good, but he's on the bench this week).

We start 2 WR, 2 RB, & 3 FLEX. My concerns are that Seattle has the #5 rush D (held Gore to nada in week 1). Right now, this is how I'm leaning:

* Harvin
* Collie
* Clayton
* Sproles
* Tolbert

Thoughts?
