Need to drop one player for a DST #2 (1 Viewer)

Scoring: 1 point per 10 yards rushed / received, 2 point bonus for 100, 150 and 200 yards, 0.5 PPR.

Roster:  QB: Cousins / Dalton; RB: Hunt / /Chubb / Yeldon /  Breida / Richard ; WR: Julio / Tate / DJ Moore / Sutton / TQ Smith

My current and only DST is the Rams which is not infallible as we saw this past weekend. Thinking of picking up the Chargers for the next 3 weeks (@Oak, Den, Ari) which also covers the Rams bye week 

Question is, who do I drop? Thinking Richard since the Raiders are a mess right now. Willing to wait and see how Sutton, Moore and TQ Smith pan out and not sure I'd want to drop Yeldon yet. 

I would drop Yeldon with Fournette coming back

I would probably drop the Rams and continue to stream defenses.  No real reason to keep them.  They haven't been difference making at the position.  I would say drop Dalton but you need him this week to cover Cousins.  After this week Dalton is the easy drop.
