Am I fleecing or getting fleeced?

I have the opportunity to trade Alexander Mattison for Aaron Jones in a 10-team 0.5ppt ppr league. I’m currently 4-1 and have Rachaad White as my next RB up. I’m very deep at receiver and wanted to make an upgrade at running back.
With JJ on IR and Vikings going in wrong direction as team I think this could be a good move to dump Mattison while his stock is up.

Should I take Aaron Jones for Alexander Mattison?

You might want to wait a week, as Jones has a Week 6 bye, but in the long run, yes, that would be a profitable trade for you.
