Start/sit Barely made playoffs and need some advice

so i went with the 0 RB draft strat and kinda screwed myself dropping jones to early. anyway roster is QB-Jackson,Rivers RBs-Mark Ingram,Kerryon Johnson,Lewis,Crowell,Montgomery,Wilson Jr. WRs-Brown,Allen,Lockett,Sutton,Pettis TE-Ebron Def-Steelers K-Fairbairn. So im thinking Rivers, Ingram , Wilson Jr., Brown, Allen, Ebron, Sutton Im kinda torn on if i should play Sutton or Lockett in the flex since Lockett has been getting it done for me all year and i also dont know if anything should change if by some miracle Kerryon plays. ill also point out that as of now im a projected 4 point underdog .
