Cook/Waddle for DJ, Lockett, Melvin

Full PPR. I am getting Dalvin and Waddle. Team is deep at WR with Deebo, McLaurin, Pittman, DJ, Lockett, Marvin Jones, Ridley (fingers crossed). You start 3 WRs in this leage and my RBs are Kamara, Swift, Javonte Williams and Melvin. Thoughts on that trade?

I would do it, you probably won’t use DJ much and Lockett is still a little question mark until we see how russ comes back. Cook is an upgrade to Melvin
