Freeman/Coleman for Mixon?

Is this a terrible trade? I have Kyle Rudolph in this league as well that is why i’m sending Kittle, Olsen will ride IR till back and might even bring value come playoff time. I’m just very annoyed with Freeman, I know Mixon is the bell cow back who i will start every week. Although he just had surgery and i dont own G. Bernard so there’s a ton of risk. Is there another RB is should target with this duo? Thoughts and intelligent feedback are much appreciated. Goal is to get true RB1.
