Trade Funchess for Dak?

My QB is currently Kirk Cousins and since I’m not a huge fan of his playoff schedule, I am thinking of trading away Devin Funchess for Dak Prescott. My other WRs are Michael Thomas, Sterling Shepard, Demaryius Thomas, and DeVante Parker.

I know it’s not the best value, but do you think it would work well for my team?
