Grading drafts immediately is a time-honored and mostly ridiculous pastime that we all enjoy immensely. The standard post-draft grade, performed mostly by draft industrial complex yokels, relies entirely on stating whether or not the grader liked or disliked they players a team picked. There is literally no point in reading grades of this nature, because even NFL front offices and scouts realize (for the most part) that they are playing a game of chance, and that even they won’t know how they did for a few years.
It’s okay to have some level of “I liked this guy” in your grades, but the only meaningful way to grade a draft is to grade the process rather than the player.
