It's doable but you are really just trading for tradings sake as it really doesn't help your team and I like Cooks more than Lewis. Plus Ertz's numbers have been a little on the decline lately. I would pass.
I think this is a terrible trade for you. I think Hunt>Zeke and Cooks>>>>>Lewis and Ertz is less risky than Gronk but not necessarily better. I think this hurts you a lot more than helping you. I would easily pass.
