Burkhead droppable?

Full PPR league with 2RB, 2WR, 1FLEX. Limit of 4 RB per team. Is Burkhead droppable with Gio, Lindsay, and Powell all on the waiver wire? Other RB are DJ, Kerryon, and Coleman. Tired of the New England trickery! Thanks folks.

Only 4 rbs is just an awful thing but yea i think i would drop rex for any of those guys.
My order would be

At least you know what you’re getting with Powell, he’s the starter. I would drop for Powell i also agree with you i am tired of the trickery
