Trade away RB for WR - Cook for Freeman/Kupp

I’m hurting at TE and WR. I have a guy in my league that keeps trying to trade. His last offer was Freeman and Kupp for Dalvin Cook. What players would be a fair exchange?

My Roster - Bell, Cook, Kerryon, Sanders, Monty , OJ Howard, Djax, Hollywood, Robby Anderson, DJ Metcalf, and McLaurin

His Rost - Conner, White, D Hop, Fitzgerald, Waller, Freeman, Kupp, AB, E Saznders, AJ Green, Mark Andrews

I wouldn’t trade Cook or Bell if I were you. They are their teams offenses.

What about trying to trade Kerryon for AB?
