Aaron Rodgers/James Conner--> Dak Prescott

I have Matt Stafford and Aaron Rodgers in a 2 QB league. I have plenty of depth at RB and WR since everyone went QB heavy early but with both my QBs on bye next week I need to pick up some alternatives. I got Nick Foles/Justin Herbert off of waivers. I have Kamara, Gurley, Montgomery and Fournette outside of Conner.

Is this trade worth it or should I hope for the best with those guys and keep the current squad?
