It's not just ESPN that says Fairley is the #1 rated guy, BTW. My point was regarding your previous post is it's hard not to take the BPA sitting on the first pick. NOW, whether that pick is a fit for your team is where the nuance comes in. Sitting at #1 overall any of the top 2-3 picks are the BPA, especially this draft and need IS paramount when the can select anyone you want.
I'm just using ESPN as a point of reference, I'm just pointing to the general media's perception of him. As to the rest of the your post, here is where I disagree. Just because he may be the 3rd best player in the draft (which I wholeheartedly disagree btw, I think he's a project and a half), does not mean he's the BPA. Even if I were to put him in the best possible light I can, while being fair to his shortcomings, I still don't have him in the same tier of talent as Green and Peterson. Small tier I know, but I think it's a fair one. Think back when Adrian Peterson was being drafted, if you had the number one pick, would you have passed on Peterson, even if you had bigger positional needs elsewhere? That is the light in which Patrick Peterson and AJ Green are put in.
