For that to happen it means the Rams
improved. That's no small thing. Because Woody is a good receiver. Robinson is just significantly better.
Robinson gives us a second Kupp type element. Big target who hauls in everything around him. Stafford can put the ball on him when he's covered in a desperate type situation and there's a reasonable chance a play gets made instead of the ball being popped up for an INT. Or he can motion Robinson deep and know he's going to go up for the ball with aggression.
The Rams are going to be more potent on offense with this change. They're a better team now. That matters.
