With the recent hirings of Aaron Glenn and Mike Vrabel, the NFL now has five coaches who once played for the teams they're now leading.

Aaron Glenn was hired to be their 19th full-time head coach on Wednesday. Glenn, who was the Jets’ first-round draft choice in 1994 and played eight seasons for the team, spent the past four years as the Lions defensive coordinator.

There are four head coaching vacancies remaining: The Dallas Cowboys, Jacksonville Jaguars, Las Vegas Raiders and the New Orleans Saints. That leaves four head coaching candidates to get hired for 2025. Let's take a look at the best ones.
