Players must have been retired for at least five years before becoming eligible. Referees and coaches must have either been retired for at least five years, or, if they are still active, have coached or officiated for at least 25 years at high-school-level programs or higher. Those being considered for induction as contributors may be inducted at any time; the Hall of Fame and its committees evaluate whether contributions are significant enough for the nominee to be inducted as a contributor.[2] Teams are also inducted at the committees' discretion.
