Trade Coleman for Ekeler?

Just curious about everybody’s philosophy when it comes to handcuffs, particularly in a dynasty league.

Specifically, I have Melvin Gordon, but not Ekeler. Would it be worth paying up, somebody like Tevin Coleman for Ekeler to have that safety net if Gordon goes down? Or is this just simply not something I should be concerned with?

Would Coleman be too much? Do you think I could get away with Coleman for Ekeler and a first round pick next year?
