Tight end help: upgrade Ertz or Fannin (if possible)

10 team full PPR. I have Ertz and Fannin Jr. (dropped Andrews right before last nights game so that’s funny… but still don’t trust him)

Competitive league and always have to keep looking to upgrade when possible. Not willing to burn a waiver claim (at #3 trying to climb to #1) but wondering if I can upgrade if current available players clear waiver.

Keep Ertz and Fannin? Or drop one for one of these guys?
