NFL rookies have become an immensly valuable commondity in today's NFL. They bring a freshness to a franchise that can get the fanbase excited and the hope that their favorite team will become a championship contender.
For NFL front offices, that excitement makes their job easier (or more difficult, depending on the team), but for them, the main benefit of having an impactful rookie comes from their salary cap number. Rookie contracts are just as valuable as the rookies themselves.
To remain competitive in the NFL, teams must maximize their salary cap window. Rookies who are able to come into the league and be starters, or meaningful contributors, can often make the difference between a playoff contender and a playoff pretender.
