One of the biggest problems is unreliable backs like Adrian Peterson (@ 49ers), Ameer Abdullah (@ Packers) and Orleans Darkwa (vs. Rams) having some of the best matchups of the week. Even Tennessee’s duo of DeMarco Murray and Derrick Henry comes with a certain amount of risk in a favorable matchup against the Ravens.

There’s a good chance you’ll need to play at least one complementary back either as your RB2 or flex, which is always a dicey proposition. Whether you’re betting on the matchup for someone like Andre Ellington (@ 49ers) or Wayne Gallman (vs. Rams) or usage for someone like Buck Allen (@ Titans) or Marlon Mack (@ Texans), you’re going to have to take a shot somehow.
