Dynasty - Bell/Conner Trade

I own Conner in a 10 team - Dynasty league that starts 1QB, 2RBs, 3WRs, 1Flex, 1Superflex, 1TE, DEF, K.
The Bell owner wants to trade me Bell for Michael Thomas. His WRs is led by Thielen and RB by Gurley/Freeman.
My other current WRs are OBJ/Cooks/Funchess/Woods. My other RBs: McCoy/all GB RBs/Carson/Powell/Burkhead. My TEs: Gronk and Ebron.
I’m leaning towards yes though I do like Thomas a lot. Thoughts?
