Two days after finishing a season in which they ranked 27th in points allowed, the Houston Texans have fired defensive coordinator Richard Smith and two other defensive assistants.

The Houston Chronicle reports that head coach Gary Kubiak fired Smith, who has been his defensive coordinator throughout his tenure in Houston, as well as defensive backs coach Jon Hoke and defensive line coach Jethro Franklin.

Per the Chronicle, Kubiak is expected to hire an experienced coordinator with a proven track record of success, as well as a coach who will employ a 4-3 defense.

It’s not clear, however, whether Kubiak will hire from outside the organization. Frank Bush, the team’s senior defensive assistant the last two seasons, could end up getting promoted to coordinator.
