Crennel, 70, began his NFL coaching career with the Giants back in 1981 as their special teams coach. He later took jobs with the Patriots, Jets and Brown before returning to New England in 2001 as their defensive coordinator.
After four seasons with the Patriots, Crennel was hired as the Browns’ head coach before he was fired four years later.
Crennel spent a few years with the Chiefs as their defensive coordinator and head coach before the Texans hired as their defensive coordinator in 2014. Houston made the decision to promote Vrabel last year and move Crennel to assistant head coach/defense.
Pagano, 50, began his NFL coaching career with the Saints in 10996 as a defensive assistant. He spent a few years with the Colts before joining the Chargers in 2002 as a defensive assistant & quality control coach.
Pagano worked his way up to defensive coordinator in 2012 and spent five years in that role before he agreed to become the assistant HC/defense for the Raiders. After Ken Norton Jr was fired as Oakland’s defensive coordinator, Pagano was promoted to defensive coordinator for the remainder of the season.
