You are right in a way. Though commenting on a recruit is not necessarily nitpicking. It can just be observations. But we have a habit of gushing over every single commitment....until later when we get more back-story about their motor, about their competition, about their habits, about the size, or when we find out our OL has sucked or our LBs are not D-1 caliber!
