Juju swap with Mack?

I’m in a situation where I’d love to improve my RB depth (like so many others) and am pretty loaded at WR. 12 team league, full PPR scoring. My current WRs are Tyreek Hill, Juju, Ty Lockett, Terry McLaurin, Marvin Jones, Robby Anderson & DJ Chark. At RB I have Zeke, Josh Jacobs, Miles Sanders & Kareem Hunt.

The other day I tried to trade Juju and Josh Jacobs for Marlon Mack & Joe Mixon unsuccessfully. What are all of your thoughts on a straight up Juju for Marlon Mack deal? The Marlon Mack owner is pretty loaded at RB…
