Drop either Tevin Coleman or Kelvin Benjamin to add Joe Mixon?

Mixon popped up on waivers (available 10/12). know he’s been frustrating, but worth a waiver claim (9 of 12)? And if so, would you drop Tevin Coleman or Kelvin Benjamin. My RBs are Gordon, Hunt, Darkwa and Coleman. My WRs are K Allen, Jeffery, Shepard, Parker, and K Benjamin. Any other week I’d consider dropping Darkwa or Shepard but need both to start this week.
