This is my problem with him, which is more of my problem with the franchise. He's a "VP of Football Operations" type not a GM. I am not impressed with our scouting department. Either a new GM needs to be hired where all he focuses on his constructing the roster, or a more competent scouting and personal department needs to replace the current one.
I wouldn't even care what the title of this "GM" would be as long as his sole responsibility was designing the team. I'd be happy with Bruce Allen being the face of the franchise so Dan doesn't have to be and doing all of that stuff that you mentioned in your post.
Bruce Allen seems like a fine guy to have around, but hasn't proven his meddle with roster construction. With all of his other duties, I don't know how he can possibly put in the work required to construct a superior roster.
