NFL teams are conducting top-30 visits with draft hopefuls this month while also doing medical rechecks on players flagged at the combine. Final preparations are being made as teams build their respective boards. It is important for fans to know how those big boards are developed. First and foremost, they will not have 100s of prospects on their boards. Instead, it will be a more finely pruned list in the range of 150 total. Those players are arranged by where the team would feel comfortable taking them but also will account for roster needs. Considerations include work ethic, medical evaluations, athleticism, production, personality and many other qualities, but the conversation begins with whether or not the prospect is a fit for what that specific team wants to do on offense or defense. In today's thought exercise, we explore positional needs and what each team may hope to accomplish in the first round.
