if the other team's top CB had to cover a different receiver, and Parker was on their 2nd best CB, forget about it.Keep him. In '20, teams focused on him, Get a WR who can get separation and YAC and DVP gets to play with someone else getting the focus. He's a good receiver, but every receiver will be more productive when he's not being targeted by the D.
800 yards, 12+yds average. Teams just don't walk away from that production.
