DK for Cooper?

I have DK and got offered Amari Cooper for him. Should I do it? it’s a close call between the two of them, full PPR

Cooper is so boom or bust and I feel like he has been for years. I like the consistency of DK. I know he’s up and down too, but the way CeeDee Lamb is playing, I’m concerned that Cooper is not going to have as many opportunities to break a big play as he has in the past. If it were me, I’d hang on to DK and give the offense a little more time to get going.
