Trade Advice for playoffs

My league allows for trades until Friday…

I’m in first place, and for the most part have been playing Wentz all year. He’s got a good schedule coming up, but I’m concerned with his week 16 against the Cowboys.

I have A Cooper and DJ Chalk and have to start one. I have the opportunity to trade A Cooper for Russel Wilson. Will making that trade win me the championship? Or should look to stream week 16 with someone like Fitz or Jones and keep my WRs? Thanks.
