I am in a league that starts 1 RB, 1 WR, and two flex positions. It is a PPR league (1 pt per reception).

My RB's are:

Matt Forte (vs Steelers)

Kevin Smith (vs Vikings)

Fred Jackson (vs Bucs)

Ray Rice (vs Chargers)

Ronnie Brown (vs Colts)

My WR's are:

Randy Moss (vs Jets)

Reggie Wayne (vs Dolphins)

T.J. Houshmandzadeh (vs 49ers)

Santana Moss (vs Rams)

Bernard Berrian (vs Lions)

I plan to start Randy Moss (WR) and Reggie Wayne (flex).

Who should I start at the RB position and the other flex position?
