My post was more tongue-in-cheek, but if the Browns happened to trade for Cousins they would extend his contract.
Also, there is no measurable statistic where Baker really comes close to Cousins' numbers. This isn't me saying Cousins is elite. Cousins is very consistent. Stefanski knows Cousins well. Who knows how Berry would perceive the idea of trading for Cousins, but I am sure it's something they would explore.
I posted this article before, but worth a read because Cousins really is a polarizing QB.
