Today, Zay. By a gigantic margin. Andrews has probably 2-3 good years left in him.
I'm sure he would get doubled over Zay. Zay is a rookie, and Andrews is a veteran. If Tyreek Hill was on this team, Andrews doesn't get doubled. Nor would he with any of about 10-15 other stud WRs league wide.
He gets doubled, in part, because of his peers on this team. And when the peers on this team improve, like they have this year, he gets doubled less. And when the peers on his team improve, like they have this year, he becomes less critical to the offense's success.
