Good draft evaluation starts with a specific question: what can this player do reliably on an NFL field? Production matters, but traits, role, competition, and context explain how that production happened.
Separate what a prospect is today from what he might become. Immediate role, developmental ceiling, and scheme fit are different parts of the projection and should not be collapsed into one grade.
The goal is not to predict every pick. It is to build a repeatable process that explains strengths, limitations, and the situations most likely to help a player succeed.
