text: 2002 NFL Draft 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.

text: 2013 Houston Texans season 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.
