Drop Martin, Pick up Crowell? (1 Viewer)

14-team PPR league. I would have to drop a RB to pick up a RB the way the rules are set. I have Zeke Elliott who I don't want to drop because he'll be back for the 2nd round of my playoffs, have Devonta Freeman, Melvin Gordon and Doug Martin. I like Martin but...should I drop Martin and pickup Crowell?

Thoughts?

Thanks.

Martin is droppable

Crowell has a better floor but his ceiling is capped by Johnson.

Martin has the potential for the highest ceiling but also has potential for a low floor

So it depends on what you are looking for...
