Mixon for Rex Burkhead and Royce Freeman

I am currently a RB whisperer with no RB for the next 2-4 weeks. I have Davonta Freeman, Joe Mixon, Buck Allen, John Wilkins, and Ito Smith. 14 team league so there is no one on the waivers lol

Trade offer is: I was offered Mixon for Rex and Royce Freeman.

Should I cave or stick with Ito Smith/J Wilkins and Buck Allen?

Currently 2-0 so I am not desparate but maybe in the next 2 weeks
