Trade for better TE?

I drafted Trey Burton as my starting TE. I have Eifert as a backup in a half PPR league. I’m happy with my RB/WR core and although it’s only week 2, I want to make sure I have a solid starter in the TE position. Should I trade for a better TE and if so would me trading Burton and Barber/Burkhead/Miller for Zach Ertz be a fair trade? Could I get a better TE than Etrz with this trade? I have plenty of RB depth with Johnson, Collins, Miller, Barber and Burkhead. This is my first year playing fantasy so trades are tough for me to judge.

Thank you!
