With the hirings of Glenn and Mike Vrabel by the New England Patriots during this cycle, the NFL has five coaches who once played for the teams they're now leading. They join Detroit's Dan Campbell, Houston's DeMeco Ryans and the Los Angeles Chargers' Jim Harbaugh.

Aaron Glenn had no doubts about where he wanted to go once the New York Jets’ head-coaching job became available. Home sweet NFL home.

The NFL is a fickle business and nothing shows that more than Bobby Slowik's firing by the Houston Texans. As the offensive coordinator in a team with a defensive head coach, DeMeco Ryans, he was widely credited with establishing an offense that brought out the best in rookie quarterback C.J. Stroud last year.
