In 1987, Adams threatened to move the Oilers to Jacksonville, Florida (now the home to the Jaguars) unless significant improvements were made to the Astrodome. Harris County, which owns the Astrodome, responded with a $67 million renovation that added 10,000 more seats, a new Astroturf carpet and 65 luxury boxes. Adams promised that with the new improvements, he would keep the team in Houston for 10 years. These improvements were funded by increases in property taxes and the doubling of the hotel tax, as well as bonds to be paid over 30 years. (As of 2011, Harris County and its taxpayers are still paying off the debt from the Astrodome renovations.) That same year, the Oilers seemed to right themselves on the field. They made the AFC playoffs every year from then until 1993, but each time they fell short of making it to the Super Bowl. After Adams made good on a threat to hold a fire sale if the Oilers did not make the Super Bowl after the 1993 season, the Oilers finished with the worst record in franchise history a year later. They would be barely competitive for the rest of their stay in Houston.
