Trade Gibson for Mitchell or Gibson+Chubb for Cordarelle Eli Mitchell and Darell Williams?

I received an offer to get Darrell Williams Cordarelle and Eli Mitchell for Chubb and Gibson, and reached out to the owner and he said he would do Gibson for Mitchell one for one. This is a no PPR league, thoughts? I feel like Gibson for Mitchell may be a no brainer, but I have the Mckissic handcuff which is making me drag my feet. Not huge on the idea of offloading Chubb but its an intriguing offer. Only other RB on my roster is Darell Henderson. Help me I am super indecisive

I technically also have Penny, didnt think that was relevant though
