I need trade advice!

I was offered Dalvin Cook, Alshon Jeffery, AJ Green, and Drew Brees for Saquon Barkley (my best rb) and Devante Adam’s (my best wr). Matt Ryan is my current QB so Brees would be and upgrade. The only downside is losing Barkley but is that worth it for the improvements everywhere else?

It’s also a dynasty league.
