I got a few.
WR: Start 1
Torrey Smith, BAL
Kenny Britt, TEN
Alshon Jeffery, CHI
WR: Start 1
DeSean Jackson, PHI
Dez Bryant, DAL
Vincent Jackson, TB
RB: Start 1
Darren McFadden, OAK
Donald Brown, IND
Usually you start McFadden without question, but two shaky performances in a row and going against a tough Steelers D is a questionable match-up for him. Brown is an average RB, but the Jacksonville match-up is favorable IMO.
RB: Start 1
Kevin Smith, DET
Jamaal Charles, KC
Charles has struggled so far and Smith continues to do well in the Motor City. Charles aggravated his surgically repaired knee so he's a bit iffy.
