WR and QB require chemistry, it does not happen overnight.
Unless you got a Tom Brady throwing or a seminal talent: ala Antonio Brown, I think a mid-season WR trade is very likely to yield little, and we know AB ain't comin' here--thank God. Two firsts for a blue chip WR seems insane to me, even a single first, unless it is a Mike Evans type, but personally, I think that guy is so full of himself, tends to be a malcontent and does not get separation. His talent is undeniable though.
If we want to help this team, we get a legit pass rusher, another linebacker to backup Milano or look for value, high possible upside cast-offs. But every new addition means someone has to go.
Two firsts for a certain DE/LB in Denver, that is a pool I'd swim in, maybe.
