Having Swift as your RB3 is nice.
If you're wanting to upgrade at WR, I would maybe try and package Zeke and JuJu to do a 2 for 2 that upgrades you at WR and still gets you a decent RB back in return as well.
You could maybe even try and pair Swift with one of your WR's instead of Zeke and do a 2 for 2 that upgrades you at WR, and gets you to keep Zeke.
