Trade value: Tarik Cohen

I managed to get Tarik Cohen on the waiver wire (standard league), and I’m trying to decide if I trade him for a WR what should I expect?

On a more general note, how do you analyze trades? This site has a nice projection for the week, but are there projections for the whole season so you can gauge trade value for a player?

You could try and see what you think.

I traded Cohen away in a standard league with Crowell for Jordy Nelson.
