Video: Ranking Every Week 6 Wide Receiver as a Start or Sit
I'm going to put Jaylen Coker in the dub flex category, very much flexible, very much playable immediately after the missed time with the quad injury.

Jaylen Coker is a playable dub-flex option after his injury

Jaylen Coker is considered a playable 'dub-flex' option, immediately viable following his return from a quad injury, though his presence in the lineup may impact the target share of other receivers.
