Question: The 2005 Houston Texans fired the only person to serve how many different NFL expansion teams as inaugural head coach?
Context: The Houston Texans season was the franchise's 12th season in the National Football League.  The Texans failed to improve upon their 12–4 record from 2012, suffering through a season-ending 14-game losing streak following a 2–0 start and missing the playoffs for the first time since 2010.  Head coach Gary Kubiak was fired after eight seasons following their eleventh loss (Week 14 vs. the Jacksonville Jaguars).  Defensive coordinator Wade Phillips was named the interim head coach for the final three games of the season.  Their 14-game losing streak is the worst in team history.  Coming off a franchise-best 12–4 record just the year before, the Texans tie a league record with the Houston Oilers (who, coincidentally, also went 12–4 in 1993 and 2–14 in 1994) for the biggest season-to-season decline in win total.  On January 3, 2014, claiming that "I'm ready to kick 2013 the hell out the door", Texans owner Robert McNair announced that former Penn State head coach Bill O'Brien would be the Texans' third head coach. Jabari Issa (born April 18, 1978) was a defensive lineman at the University of Washington, drafted in the 2000 NFL Draft by the Arizona Cardinals where he played from 2000-2001.  Issa's career also included NFL stints with the Houston Texans (taken in the 2002 NFL Expansion Draft), Pittsburgh, and Kansas City, the NFL Europe Barcelona Dragons, and the CFL including a Grey Cup Championship with the Edmonton Eskimos. The 2002 NFL draft was the procedure by which National Football League (NFL) teams selected amateur college football players.  The draft is known officially as the "NFL Annual Player Selection Meeting" and has been conducted annually since 1936.  The draft took place April 20–21, 2002 at the Theater at Madison Square Garden in New York City, New York.  The draft was broadcast on ESPN both days and eventually moved to ESPN2.  The draft began with the Houston Texans selecting David Carr, and it ended with the Texans selecting Mr. Irrelevant, Ahmad Miller.  There were thirty-two compensatory selections distributed among eighteen teams, with the Buffalo Bills receiving the most selections with four.  The University of Miami was the college most represented in the draft, having five of its players selected in the first round.  Although the Carolina Panthers finished with a 1–15 record which would normally have given them the first pick in each round, the Houston Texans were given the first pick because they were an expansion team.  The league also held a supplemental draft after the regular draft and before the regular season. The 1960 NFL expansion draft was the first National Football League (NFL) draft in which a new expansion team, named the Dallas Rangers, selected its initial players.  The NFL awarded Dallas, Texas a franchise to compete for revenue with Lamar Hunt's Dallas Texans of the upstart American Football League.  The Dallas expansion franchise was approved too late for it to participate in the 1960 NFL draft which had been held on November 30, 1959.  Dallas is the only NFL expansion team to not have had the benefit of a college draft in its first year. The 2002 National Football League expansion draft is the most recent National Football League (NFL) draft in which a new expansion team, named the Houston Texans, selected its first players.  On October 6, 1999, in Atlanta, NFL owners had unanimously voted to award the 32nd NFL franchise and the Super Bowl XXXVIII to the city of Houston, Texas.  So that the Texans could become competitive with existing teams, the league awarded the Texans the first pick in the 2002 NFL Draft and gave them the opportunity to select current players from existing teams.  That selection was provided by the expansion draft, held on February 18, 2002. Ernest Dominic Capers (born August 7, 1950) is an American football coach and the current defensive coordinator for the Green Bay Packers of the National Football League (NFL).  Capers served as the head coach for the NFL's Carolina Panthers from 1995 to 1998 and for the Houston Texans from 2002 to 2005.  He is the only person to serve two different NFL expansion teams as their inaugural head coach. The Houston Texans are a professional American football team based in Houston, Texas.  The Texans compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) South division.  The club first played in as an expansion team, which makes them the youngest franchise currently competing in the NFL.  The Texans replaced Houston's previous franchise, the Houston Oilers, which moved to Nashville, Tennessee and are now the Tennessee Titans.  The team's majority owner is Bob McNair.  While the team mainly struggled in the 2000s, they clinched their first playoff berth during the 2011 season as AFC South division champions.  The Texans have gone on to win more AFC South championships in 2012, 2015, and 2016.  To date, the Texans are the only NFL franchise to have never played in a conference championship game. Romeo Crennel (born June 18, 1947) is an American football coach who is the assistant head coach  for the Houston Texans of the National Football League (NFL).  Though he has spent much of his career as a defensive assistant, he has also been the head coach of the Cleveland Browns and the Kansas City Chiefs.  On January 20, 2014, he became the defensive coordinator for the Houston Texans.  He was promoted to assistant head coach prior to the 2017 season. The 2005 Houston Texans season was the fourth season in franchise history.  The Texans completed the season with the worst record in franchise history (a record that would later be matched in 2013).  This led to the Texans obtaining the first selection in the NFL Draft for the second time since the franchise formed in 2002.  The team fired head coach Dom Capers after the season; he was replaced by Denver Broncos offensive coordinator Gary Kubiak. This is a list of seasons completed by the Jacksonville Jaguars American football franchise of the National Football League (NFL).  The list documents the season-by-season records of the Jaguars' franchise from to present, including postseason records, and league awards for individual players or head coaches.  The Jaguars, along with the Carolina Panthers, joined the NFL as 1995 expansion teams. Jacksonville is one of only two teams, the other being the Houston Texans, never to have played in either a Super Bowl or any other NFL Championship.
