A Little Dynasty Help

Fellow Footclan. I’m in a MyFantasyLeague dynasty and I’m trying to figure out a trade. The trade is Mixon with a 5 year contract, Chris Thompson with a 2 year, and Chris Hogan with a 1 year, for his Amari Cooper with a 5 year contract. Here’s the rest of my roster with the number of contract years they have left.

Kareem Hunt 5 years
Doug Martin 5 years
Jerick McKinnon 2 years
Frank Gore 1 year
Mike Gillislee 1 year
Chris Carson 5 years
Danny Amendola 2 years
Kelvin Benjamin 2 years
Golden Tate 2 years
Demaryius Thomas 1 year

I wanted to make some sort of move before last night but I hesitated and of course Cooper goes off.

Any help would be appreciated!
