RB2 help! Shed some light!

Best options available are Kerwynn Williams against Tennessee with Peterson out, Theo Riddick against Tampa Bay with Abdullah supposedly out and Stafford as an unknown, or Doug Martin against Detroit with all of his issues lately?

This one is killing me fellas, help me out.

Thanks.

theo especially if ppr. and no question if abdulah is out again

Theo if abdulah sits, then Williams, then Martin
