What is the contract duration for 1st-round draft picks in the NFL?

1st-round draft picks in the NFL are signed to contracts that typically last for 4 years. This duration was established as part of the collective bargaining agreement, which provides a structured guideline for rookie contracts. These contracts also include a fifth-year option that can be exercised by the team for players who have performed well during their first few seasons, allowing teams to retain standout players beyond the initial 4-year term. This 4-year duration is standard for 1st-round picks, aligning with the NFL's approach to managing rookie contracts and player salary caps.
