Amari Cooper for Edelman?

Thoughts on offering one of Amari Cooper/Matt Brieda/Sanders for Edelman? Standard league

edelman is worth more than any of the guys you are selling… Cooper sucks so much, im trying to get rid of him as well. Breida hurt his knee sunday and sanders plays for a QB that cant do anything right(im a broncos fan). To get edelman you would probably need to package at least 2 of these 3 players.
