On Monday, Arizona Cardinals president Michael Bidwill refused to provide a timetable for the hiring of the team's next head football coach.
But it's safe to say the Cards have hit the ground running in their search to replace Steve Wilks, who was fired Monday after his first season in Arizona.
The Cardinals are set to interview at least five candidates for the job, according to reports. Two other candidates -- Chiefs offensive coordinator Eric Bieniemy and former Packers head coach Mike McCarthy -- have reportedly declined an interview with the team.
Here's what you need to know about each candidate, in no particular order.
1. Zac Taylor (Current job: Quarterbacks coach, Los Angeles Rams)
The 35-year-old Taylor is the youngest candidate on this list; he's just three months older than Larry Fitzgerald. He has spent each of the last two seasons with the Rams, as assistant wide receivers coach in 2017 and quarterbacks coach in 2018. He previously served as offensive coordinator and quarterbacks coach for the Miami Dolphins and Cincinnati Bearcats. A former quarterback at Nebraska, Taylor has no previous head coaching experience. Other teams reportedly interested: Cincinnati Bengals
2. Dan Campbell (Current job: Assistant head coach, New Orleans Saints)
The 42-year-old Campbell has been the Saints' assistant head coach since 2016. He spent the previous six seasons with the Miami Dolphins, and he was the Dolphins' interim head coach for 12 games in 2015, leading Miami to a 5-7 record. He played as a tight end at Texas A&M and for four different NFL teams from 1999-2009. Other teams reportedly interested: Green Bay Packers, Cleveland Browns
3. Adam Gase (Current job: None)
The 40-year-old Gase was the Dolphins' head coach from 2016-18 and posted a 23-25 record, including a 7-9 mark in the 2018 season -- but the Dolphins fired Gase on Monday. Gase has also served as the offensive coordinator for the Chicago Bears and Denver Broncos. He was a quarterbacks coach for the Broncos and Detroit Lions. Other teams reportedly interested: New York Jets
4. Kliff Kingsbury (Current job: Offensive coordinator, USC)
The 39-year-old Kingsbury was recently fired after posting a 35-40 record in six seasons as head coach at Texas Tech. He accepted the offensive coordinator position at USC on Dec. 5. Before Texas Tech, Kingsbury was an offensive coordinator and quarterbacks coach at Houston and Texas A&M, where he worked under current Arizona Wildcats head coach Kevin Sumlin. He was a quarterback at Texas Tech and spent time as a QB with the Jets, New England Patriots and New Orleans Saints. Other teams reportedly interested: New York Jets.
5. Jim Caldwell (Current job: None)
At 63 years old, Caldwell is by far the oldest candidate on this list, and he has the most head coaching experience. He was the head coach of Wake Forest from 1993-2000 and had head coaching stints at the NFL level with the Tampa Bay Buccaneeers, Indianapolis Colts and, most recently, Detroit Lions. Like several other candidates on this list, Caldwell, a former defensive back at Iowa, has served as a quarterbacks coach, and he has been a part of two Super Bowl championship teams in that capacity -- the Colts in 2007 and the Baltimore Ravens in 2013. Caldwell has a 62-50 overall record and made four playoff appearances as an NFL head coach. Other teams reportedly interested: Green Bay Packers, Cleveland Browns, New York Jets
