The Houston Texans are going to have a new head coach at the helm next season and they've already begun their interview process. According to the team's official Twitter account, the Texans have interviewed Jim Caldwell for their head coaching vacancy on Monday.

Earlier this season, the Texans parted ways with Bill O'Brien after being with the franchise since the 2014 campaign. O'Brien also held the general manager role as he compiled a 54-52 record in seven seasons, including the playoffs.

Following O'Brien being fired, Houston named Romeo Crennel the interim head coach. Due to the improvements that the team has shown to finish the season, the Texans have discussed the possibility of promoting Crennel to head coach in 2021.

On the other hand, the interview with Caldwell happened on Monday, with the Texans able to conduct one since Caldwell isn't currently employed. Caldwell's most recent job in the NFL was the assistant head coach and quarterbacks coach of the Miami Dolphins in 2019.

However, before that — and as the Texans might know — Caldwell was one of the best coaches that the Detroit Lions have had in their history. Despite coaching just four seasons with the Lions from 2014-2017, Caldwell posted an impressive 36-30 record in Detroit, which includes two playoff appearances.

Besides being the last coach to lead the Lions to the postseason, Caldwell has the fifth-best winning percentage among coaches in Detroit's franchise history. While the likes of Eric Bieniemy and Brian Daboll have been rumored as candidates for the Texans, Caldwell will also be considered for the head coaching position.

The fact that the Lions have struggled so much under Matt Patricia, and are now searching for a new coach in their own right, casts Caldwell's tenure there in a different light. It is therefore not terribly surprising the Texans might consider Caldwell, though Houston fans would most likely prefer Bieniemy as the offensive wizard who can maximize the talents of Deshaun Watson.
