Looking for straight Wr trade, Adam Thielen for???
Straight position-for-same-position trades are hard to pull off, minus the use of additional draft picks. Remember, somebody went to the trouble of drafting or adding the WR they got, so they have an emotional investment. The only way for it to work is if you get someone who has underperformed and the owner is looking to dump them.
Off the top of my head, Aiyuk comes to mind as somebody like that, but I still think he has potential.
