Adams convinced Tampa Bay owner Hugh Culverhouse to trade him the rights to Heisman Trophy-winning running back Earl Campbell in 1978.
The Campbell-led teams reached two straight AFC title games, only to lose to eventual Super Bowl winner Pittsburgh each time. The Oilers flamed out of the playoffs early in 1980 and Adams fired popular coach Bum Phillips, a move that permanently alienated him from many fans of the team’s “Luv Ya Blue” era. Phillips died Friday, also at the age of 90.
Adams complained about the Astrodome in 1987 and toured the Gator Bowl in Jacksonville scouting a possible move before getting the 10,000 extra seats he wanted in Houston.
The Oilers had their longest run of success in the late 1980s and early 1990s after signing Warren Moon in 1984. They became best known for blowing a record 32-point lead in a playoff game at Buffalo on Jan. 3, 1993 — Adams‘ 70th birthday.
Renamed the Titans, his franchise reached its lone Super Bowl after the 1999 season only to lose to the Rams 23-16 when Kevin Dyson was tackled at the St. Louis 1-yard line as time expired. The Titans made a second AFC championship game after the 2002 season as part of six playoff berths, the last in 2008.
His wife Nancy died in 2009. He is survived by daughters Susie Smith and Amy Strunk, and seven grandchildren. Another son, Kenneth Stanley Adams III, died in 1987 at age 29.
