It is easy for Buffalo Bills fans to get carried away with each and every pick during any given NFL Draft. To be fair, those paid to cover the event get carried away as well.
Picks are immediately deemed reaches or great steals, without much context.
However, it takes at least three years before it is fair to truly grade a draft class. Players need time to learn in the NFL and three years is enough time to see if a player is still a building block for the future, or if they are going to be let go.
