Redraft Trade involving CMC

Will be 4-4 after Week 8 and just out of the playoffs. Full PPR 12 team league. CMC and Aiyuk will be on bye. My other flex players are Henry, Waddle, Diontae, Doubs, Dell, Singletary. The trade proposal is:

I receive: Ja’marr Chase, David Montgomery, DK Metcalf
They receive: CMC, Diontae Johnson.

Obviously CMC is a ringer, but thoughts?
