For what it's worth.. my opinion on those you listed:
"Goff's picking up the offense quickly.." - - I can't imagine he's NOT getting better if for no other reason than it's his second year... and I think there's a lot more than that.
"Gurley ready to be the horse again.." This one I don't know. I'm worried about Gurley.
"Kupp is smarter than Al Einstein (j/k) and is correcting the coaches.." Doesn't surprise me... someone mentioned "Faulk" today in a post... ?? Can't remember who.. but good point. A smart football player WOULD stick out, I think. We aren't used to it.
"Olgetree making smooth transition to 3-4.." This is the least doubtful of them all, for me... as far as it being 'accurate'. I think it fits him to a tee.
