TE question on 12 team .5ppr deep bench league

This is a 12 team, 20 player roster league and I grabbed Walker and Waller late. Only grabbed two due to the deep bench and max on position spots. Someone dropped Ebron and now he is a free agent. I am wondering if I should drop Waller for Ebron or just say screw it and go with what I have.

I personally want nothing to do with colts pass catchers this season. You’ve got a perennial set it/forget it player in walker. If waller pops off like everyone believes you’ll be golden.
I am hoping it happens week 7, because I am aiming to pick him up then after his bye and make him a set it/forget it player.
